Site Gateway provides a visual, Caddy-powered control plane for static sites, proxy routes, redirects, raw TCP/UDP streams, HTTPS, health checks, access control, and recovery — covering everything from a single ZIP upload to a full homelab of proxied applications.</p><h3>How this manual is organized</h3><p>Each area below has an <strong>overview</strong> article (what it’s for and how to configure the common case) followed by a <strong>field reference</strong> article covering every advanced control, one at a time. Use the sidebar to jump straight to a section, or search for any field name, error message, or setting — search matches headings, body text, and field names together.</p><h3>Novice path</h3><p>Create one route, test it locally, then add a domain and TLS. Keep defaults until you have a reason to change them.</p><h3>Expert note</h3><p>Configuration is stored in SQLite under <code>/data</code> and every generated Caddy configuration is validated before reload — if validation fails, the previous working configuration stays active and the failure is explained in Gateway Events.</p></article><article data-doc="getting started install first login setup administrator"><p class="eyebrow">Getting started</p><h2>From installation to your first route</h2><p>Install the container with persistent <code>/data</code> storage, open the management port (<code>8080</code> by default), and complete the administrator setup screen shown on first launch. Before publishing public domains, confirm DNS already points to this server and that ports 80 and 443 are free for Site Gateway to use.</p><h3>Choosing your first route type</h3><ul><li><strong>Hosted Site:</strong> you have static files (a ZIP or a single <code>index.html</code>) and want Site Gateway to serve them directly.</li><li><strong>Proxy Host:</strong> you already have an application running somewhere — another container, a LAN device, another server — and want a domain and HTTPS in front of it.</li><li><strong>Redirect Host:</strong> you want a domain to simply forward visitors to a different address.</li><li><strong>Streaming Host:</strong> you need to forward a raw TCP or UDP port (SSH, Minecraft, a game server) with no domain and no HTTPS involved.</li></ul><h3>Example</h3><p>Publish a ZIP on a direct port first so you can confirm it works over LAN, then add <code>www.example.com</code> once DNS and port forwarding are ready and Automatic HTTPS can issue a certificate.</p></article><article data-doc="dashboard overview metric strip live health runtime system scheduled jobs needs attention recent activity public ip throughput"><p class="eyebrow">Dashboard</p><h2>What each panel is telling you</h2><p>The Dashboard is a glance-and-go summary — every number and status on it links back to a full section elsewhere, so you never have to act on the Dashboard itself.</p><h3>Metric strip</h3><p>Counts of Hosted Sites, Proxy Hosts, and Certificates needing attention, plus a <strong>Throughput</strong> chip showing live requests in the last minute across every configured domain — click it to open the full Performance tab.</p><h3>Live Health</h3><ul><li><strong>Reverse proxy / Certificates / Persistent storage:</strong> the original health tiles.</li><li><strong>Streaming ports:</strong> how many enabled Streaming Hosts are actually bound and listening, versus configured.</li><li><strong>Upstreams:</strong> how many Proxy Hosts are currently passing their health check.</li></ul><h3>Runtime & System</h3><p>Container and version facts, plus a <strong>Public IP</strong> tile showing your gateway's current public address, rechecked automatically every 60 minutes — prep work for future Dynamic DNS support. This is a status fact, not a job you configure.</p><h3>Scheduled Jobs</h3><p>Background jobs shown as status tiles — proxy health checks, backups, log pruning, certificate/domain readiness checks, and the Public IP check — each showing its schedule and last result.</p><h3>Needs Attention</h3><p>Lists anything that needs a decision (a failing health check, an expiring certificate). Clicking an item jumps straight to it. When nothing needs attention, the panel collapses to a single all-clear banner instead of an empty list.</p><h3>Recent Activity</h3><p>The last several configuration and operational events, with relative timestamps (“4 hours ago”). This is a shortcut, not a separate log — the same events are searchable in full under Logs → Gateway Events.</p></article><article data-doc="hosted sites overview static zip index upload configure create name domain port tls hsts"><p class="eyebrow">Hosted Sites</p><h2>Overview: publish a static website</h2><p>A Hosted Site serves files you upload directly — no separate application or container required. Use it for a static site, a single-page app build, documentation, or anything that’s just HTML/CSS/JS.</p><h3>Creating a Hosted Site</h3><ul><li><strong>Name:</strong> the label shown in Site Gateway; it doesn’t need to match the domain.</li><li><strong>Primary domain</strong> <span class="optional">Optional</span>: leave blank for port-only LAN access, or set a hostname to serve the same files there once DNS is ready.</li><li><strong>Additional domains:</strong> one alias per line — every alias serves the same files under the same TLS settings as the primary domain.</li><li><strong>Port:</strong> the direct LAN port this site answers on. Must fall inside the configured port range (shown as a hint on the form, default <code>9000–9099</code>) and not already be used by another site.</li><li><strong>TLS:</strong> <em>Automatic public HTTPS</em> (default, requires a working domain and open ports 80/443), <em>Internal HTTPS for trusted local devices</em>, or <em>HTTP only</em>.</li><li><strong>Enable HSTS after HTTPS is verified:</strong> only turn this on once you’ve confirmed HTTPS works for every client — HSTS tells browsers to refuse HTTP entirely for this domain going forward, and that’s hard to undo quickly.</li><li><strong>Website files:</strong> upload a ZIP whose root contains <code>index.html</code> (a single top-level folder inside the ZIP is automatically flattened), or upload a bare <code>index.html</code> file directly. Up to 250 MB.</li></ul><h3>Updating an existing site</h3><p>Use <strong>Replace files</strong> from the card’s menu to upload a new ZIP or HTML file without recreating the site or losing its domain/TLS/health settings. Use <strong>Domain & TLS</strong> to change the domain, TLS mode, or any advanced setting below.</p><h3>Expected behavior</h3><p>Files are served immediately on the chosen port and, once configured, through the domain as well.</p></article><article data-doc="hosted sites advanced access list compression headers hsts subdomains custom caddy configuration health monitor"><p class="eyebrow">Hosted Sites</p><h2>Advanced options and health monitoring</h2><p>Expand <strong>Advanced options</strong> on the create or edit form for these controls:</p><ul><li><strong>Access List:</strong> applies a reusable network or login restriction before any visitor reaches this site. Choose <em>Public — no Access List</em> to leave it open.</li><li><strong>Compression:</strong> <em>Automatic zstd + gzip</em> (default), <em>gzip only</em>, or <em>Off</em>.</li><li><strong>Request headers</strong> / <strong>Response headers:</strong> one <code>Name: value</code> pair per line, up to 30 each. Request headers are added before Caddy processes the request; response headers are added to what visitors receive.</li><li><strong>Apply HSTS to subdomains:</strong> adds <code>includeSubDomains</code> to the HSTS header; only takes effect when HSTS itself is on and TLS isn’t HTTP only.</li><li><strong>Custom Caddy configuration:</strong> expert-only raw Caddyfile lines appended to this site’s block, validated before reload. Lines that would touch the global config block, the admin API, storage, or <code>import</code>/<code>persist_config</code> directives are rejected outright, since those could affect every other route on the gateway.</li></ul><h3>Monitoring this site</h3><p>Hosted Sites can be health-checked the same way Proxy Hosts are: a <strong>Health-check path</strong> (default <code>/</code>), <strong>method</strong> (GET or HEAD), <strong>expected status</strong> (a code, list, or range such as <code>200</code>, <code>200,204</code>, or <code>200-499</code>), a <strong>timeout</strong> in seconds (1–60, default 4), up to 3 <strong>retries</strong>, and a <strong>Monitor this site</strong> toggle. Turning monitoring off shows the card as “Monitoring paused” instead of running a periodic check.</p></article><article data-doc="proxy hosts overview jellyfin vaultwarden plex forward upstream configure name domain target tls"><p class="eyebrow">Proxy Hosts</p><h2>Overview: connect a local application</h2><p>A Proxy Host puts a domain and HTTPS in front of something already running elsewhere — another container, a LAN device, or a remote service.</p><h3>Creating a Proxy Host</h3><ul><li><strong>Name:</strong> the label shown in Site Gateway.</li><li><strong>Primary domain</strong> and <strong>Additional domains:</strong> same behavior as Hosted Sites.</li><li><strong>Forward to:</strong> the upstream address, e.g. <code>http://192.168.1.20:8123</code>.

When present, Caddy distributes requests across every healthy target instead of using the single Forward-to address alone, and the Advanced options’ Load balancing setting controls how.</li><li><strong>TLS:</strong> Automatic public HTTPS, Internal HTTPS, <em>Custom uploaded certificate</em>, or HTTP only.</li><li><strong>Enable HSTS after HTTPS is verified.</strong></li></ul><h3>Example</h3><p>For Jellyfin at <code>192.168.1.20:8096</code>, use domain <code>jellyfin.example.com</code> and forward target <code>http://192.168.1.20:8096</code>. Site Gateway checks the upstream continuously and Caddy manages an eligible public HTTPS certificate automatically.</p></article><article data-doc="proxy hosts advanced access list health expected status timeout retries compression block common exploits security custom locations headers upstream tls server name insecure hsts caddy configuration upstream pool load balancing round robin least connections ip hash sticky sessions"><p class="eyebrow">Proxy Hosts</p><h2>Advanced options, field by field</h2><p>Most applications only need a domain, Forward-to target, and TLS choice. These controls are for applications with unusual paths, authentication needs, response codes, headers, or performance requirements.</p><ul><li><strong>Access List:</strong> applies reusable login and network rules before the upstream is reached.</li><li><strong>Health-check path</strong> and <strong>method:</strong> the request Site Gateway makes when checking this application (path default <code>/</code>; GET or HEAD).</li><li><strong>Expected status:</strong> accepts a single code, a comma list, or a range — <code>200</code>, <code>200,204</code>, or <code>200-399</code>.</li><li><strong>Timeout in seconds:</strong> 1–60, default 4.</li><li><strong>Monitor this upstream:</strong> when off, the status shows “Monitoring paused” and no periodic request is made.</li><li><strong>Compression:</strong> Automatic zstd + gzip, gzip only, or Off.</li><li><strong>Block common exploits:</strong> when enabled, Site Gateway checks the request’s URL path against one fixed, built-in pattern and responds 403 before the request ever reaches the upstream if it matches. The pattern currently checks the path for: path traversal sequences (<code>../</code> or <code>..\</code>); direct requests for <code>/etc/passwd</code>; WordPress probing (<code>/wp-login.php</code>, <code>/wp-admin/</code>, <code>/xmlrpc.php</code>); exposed config/VCS paths (<code>/.env</code>, <code>/.git/</code>, <code>/.aws/</code>); exposed PHPUnit test endpoints (<code>/vendor/phpunit</code>, <code>/phpunit/</code>); the literal strings <code>eval(</code> and <code>base64_decode(</code>; a SQL <code>UNION SELECT</code> sequence; and <code>&lt;script</code>. Matching is case-insensitive. <strong>Important:</strong> this only inspects the URL path — it does not inspect the query string, request body, cookies, or headers, so a SQL-injection or XSS payload sent as a query parameter (e.g. <code>?id=1 UNION SELECT...</code>) is not caught by this toggle. This is a small, fixed, path-only ruleset, not a full web application firewall — it will not catch every attack, cannot currently be extended with custom patterns, and should not replace keeping the upstream application itself patched.</li><li><strong>Custom Locations:</strong> send specific paths to a different upstream. One per line: <code>/api/* | http://192.168.1.20:3001 | strip</code> or <code>preserve</code> — <em>strip</em> removes the matched prefix before forwarding, <em>preserve</em> keeps it. Up to 20 entries.</li><li><strong>Request headers</strong> / <strong>Response headers:</strong> same <code>Name: value</code>-per-line format as Hosted Sites.</li><li><strong>Upstream TLS server name:</strong> an optional SNI name expected by the upstream certificate. Only meaningful when every upstream target uses <code>https://</code> — the field is disabled otherwise.</li><li><strong>Ignore upstream TLS certificate errors:</strong> use only for a trusted internal HTTPS service with a self-signed or hostname-mismatched certificate; also requires an HTTPS upstream to take effect.</li><li><strong>Apply HSTS to subdomains.</strong></li><li><strong>Custom Caddy configuration:</strong> same validation rules as Hosted Sites’ custom configuration. NGINX syntax is not supported — Site Gateway generates Caddyfile syntax.</li></ul><li><strong>Upstream pool:</strong> additional <code>http(s)://</code> targets, one per line, up to 10 — the same field described in the Overview, now editable here too on an existing Proxy Host, not just when first creating it. Once Upstream pool has any entries, Caddy uses only those targets — the single Forward-to address above is not automatically added to the pool alongside them, so include it as one of the pool lines too if it should keep receiving traffic.</li><li><strong>Load balancing:</strong> only takes effect once Upstream pool has 2 or more entries — Forward to is never counted toward this, per the note above. <em>Random</em> (Caddy’s own default) picks a target at random per request; <em>Round Robin</em> rotates through targets evenly; <em>Least Connections</em> sends each request to whichever target currently has the fewest active requests; <em>IP Hash</em> sends a given client’s requests to the same target each time (sticky sessions), useful for applications that keep session state on one backend. This only affects which upstream Caddy sends a request to — it does not change the separate Health-check settings below, which only drive Site Gateway’s own dashboard status.</li><h3>How to verify a change</h3><p>Save one setting at a time, watch the card’s upstream status line, check Access Logs, and compare against a direct request to the application. If Caddy rejects a custom configuration, Site Gateway keeps the last known-good configuration active and shows the rejection reason.</p></article><article data-doc="proxy custom certificate upload pem private key mismatch"><p class="eyebrow">Proxy Hosts</p><h2>Custom uploaded certificates</h2><p>Choosing <strong>Custom uploaded certificate</strong> as the TLS mode reveals two file fields: <strong>Certificate PEM</strong> and <strong>Private key PEM</strong>. Both are required together — Site Gateway verifies the private key’s public key actually matches the certificate before accepting the pair, and confirms the certificate’s Subject Alternative Names cover every domain configured on that Proxy Host. A certificate that doesn’t cover every alias is rejected rather than silently applied to only some of them.</p><p>Accepted files are stored under <code>/data/certificates/custom</code> and included in complete backups. Replacing a custom certificate later works the same way — upload both files again through the same field.</p></article><article data-doc="redirect hosts overview permanent temporary path query preserve configure"><p class="eyebrow">Redirect Hosts</p><h2>Overview: move an address safely</h2><p>A Redirect Host sends visitors from one domain straight to another, with no files hosted and no application behind it.</p><h3>Fields</h3><ul><li><strong>Name.</strong></li><li><strong>Source domain:</strong> the old address people currently use.</li><li><strong>Additional source domains:</strong> further aliases that redirect the same way.</li><li><strong>Destination:</strong> a complete <code>http://</code> or <code>https://</code> URL to send visitors to.</li><li><strong>Redirect type:</strong> <code>302</code> Temporary (default), <code>301</code> Permanent, <code>307</code> Temporary — preserve method, <code>308</code> Permanent — preserve method.</li><li><strong>TLS:</strong> Automatic HTTPS, HTTP only, or Internal HTTPS — this governs the source domain, not the destination.</li><li><strong>Preserve path and query</strong> (on by default): when enabled, <code>old.example.com/library?id=2</code> becomes <code>new.example.com/library?id=2</code> instead of always landing on the destination’s root.</li><li><strong>Access List</strong> <span class="optional">Optional</span>: protects the source domain the same way it protects Hosted Sites and Proxy Hosts.</li></ul><h3>Choosing a redirect type</h3><p>Use 301 or 308 only when the move is meant to be permanent — browsers and search engines cache these aggressively. Use 302 or 307 while you’re still testing the new destination.</p></article><article data-doc="streaming hosts overview tcp udp port forward raw minecraft ssh game server configure port target"><p class="eyebrow">Streaming Hosts</p><h2>Overview: raw TCP/UDP port forwarding</h2><p>A Streaming Host forwards a raw TCP or UDP port straight to another host and port — there’s no domain, no HTTPS, and no HTTP layer involved at all, unlike every other route type in Site Gateway. Use it for services that speak their own protocol directly over a port: SSH, a Minecraft or other game server, a VPN endpoint, or any similar TCP/UDP service.</p><h3>The one prerequisite: publish the port first</h3><p>Streaming Hosts listen for connections from <em>inside</em> the Site Gateway container itself — they are not routed through Caddy the way domains are. That means the incoming port must already be published on the container (added to your <code>docker-compose.yaml</code> or Unraid port mappings, with the container recreated) <strong>before</strong> you create the matching Streaming Host in the UI, or nothing outside the container will ever reach it.</p><h3>Example docker-compose port mapping</h3><p>To forward SSH (22) and a Minecraft server (25565):</p><p><code>ports:<br>&nbsp;&nbsp;- "22:22/tcp"<br>&nbsp;&nbsp;- "25565:25565/tcp"</code></p><h3>Creating a Streaming Host</h3><ul><li><strong>Name.</strong></li><li><strong>Incoming port:</strong> 1–65535. Cannot be the admin port, 80, 443, a port already inside the Hosted Sites port range, or a port already used by another Streaming Host.</li><li><strong>Forward to:</strong> a plain <code>host:port</code> address, e.g. <code>192.168.1.20:25565</code>. No <code>http://</code> — this is a raw socket forward, not a web address.</li><li><strong>TCP</strong> / <strong>UDP:</strong> enable one or both. At least one must stay checked.</li><li><strong>Monitor this target:</strong> runs a TCP reachability probe against the forward address every check cycle, even for UDP-only streams (UDP itself has no reliable way to “ping” a service).</li></ul></article><article data-doc="streaming hosts how it works tcp relay udp relay session multiplex health probe examples"><p class="eyebrow">Streaming Hosts</p><h2>How the forwarding actually works</h2><p><strong>TCP</strong> is a full one-to-one relay: every inbound connection gets its own fresh outbound connection to the forward target, and the two are piped together in both directions. Closing or erroring either side tears down the other.</p><p><strong>UDP</strong> is connectionless, so Site Gateway multiplexes many remote clients over one listening port by tracking a short-lived “session” per unique client address, each with its own outbound socket to the forward target. An idle session is cleaned up automatically after about a minute of inactivity.</p><h3>Health monitoring</h3><p>The monitor always performs a plain TCP reachability check against the forward address, with a 4-second timeout — this confirms the target host and port are reachable, not that the specific game or service protocol is fully healthy.

Assign a saved list from that route’s Advanced options.</p><h3>Fields</h3><ul><li><strong>Name.</strong></li><li><strong>Allowed networks:</strong> one IP, CIDR range, or the literal <code>private_ranges</code> per line. When set, every network <em>not</em> listed is denied — this is an allow-list, not a suggestion.</li><li><strong>Denied networks</strong> <span class="optional">Optional</span>: evaluated <em>before</em> allowed networks and logins, so a denied entry always wins even if it would otherwise be allowed.</li><li><strong>Logins:</strong> add one or more username/password pairs directly on the Access List (passwords need at least 8 characters; leaving a password blank while editing an existing login keeps it unchanged).</li><li><strong>Groups:</strong> alternatively, let members of a Group (Administration → Users & Groups) authenticate with their own Site Gateway username and password instead of a separate Access-List-only login.

An Access List can’t be deleted while anything still references it — unassign it from every host first.</p></article><article data-doc="users groups overview administrator standard viewer role reset password archive audit group enable disable toggle access"><p class="eyebrow">Users &amp; Groups</p><h2>Overview: control who can change the gateway</h2><p>Every account has a role:</p><ul><li><strong>Administrator:</strong> full access, including Users, Groups, Settings, and Backups.</li><li><strong>Standard User:</strong> can manage Hosted Sites, Proxy Hosts, Redirect Hosts, Streaming Hosts, and Access Lists, but not Users, Groups, Settings, or Backups.</li><li><strong>Viewer:</strong> read-only — can inspect everything but change nothing.</li></ul><h3>Creating a user</h3><ul><li><strong>Display name.</strong></li><li><strong>Username:</strong> 3–64 characters, letters/numbers/<code>._-</code>, must be unique.</li><li><strong>Role.</strong></li><li><strong>Temporary password:</strong> at least 8 characters — share it securely and have the person change it after their first sign-in.</li></ul><h3>Managing an existing user</h3><p>An administrator can change a user’s role from the card’s role dropdown, reset their password, archive them (a reversible soft-disable distinct from deleting), or delete them outright. Delete and Change icon live under the card’s “•••” menu, matching Hosted Sites and Proxy Hosts; role, password reset, and archive stay as visible buttons. You cannot disable, archive, delete, or change the role of your own account — another administrator has to do that — and Site Gateway always keeps at least one active Administrator, refusing any action that would leave zero. Resetting a user’s password here does not disable their two-factor authentication if they have it enabled — see My Account for how 2FA works. There is currently no administrator-side way to turn off another user’s 2FA; only that user can, from their own My Account page.</p><h3>Groups</h3><p>A Group is simply a named set of users. Its only purpose is authentication: assign a Group to an Access List so its members can log in with their own Site Gateway credentials instead of a separate Access-List-only login.</p><p>Every Group has its own enable/disable toggle, separate from deleting it. <strong>Disabling a Group immediately stops it from granting access through any Access List it’s assigned to</strong> — the assignment itself is untouched and still shows as assigned, but its members can no longer authenticate through it until the Group is re-enabled. This is a common surprise: disabling a Group is not the same as archiving it for later cleanup, it has an immediate access-control effect. If the Group is currently assigned to at least one enabled Access List, disabling it now asks for confirmation first, naming exactly which Access List(s) will stop authenticating that Group’s members — the same pattern already used when disabling an Access List that protects active hosts.</p><h3>Audit history</h3><p>Administration includes an Audit log — a searchable, filterable, immutable record of who did what, filterable by outcome (success/failed) and free-text search across the user, action, and target. Audit entries can’t be edited or deleted.</p></article><article data-doc="my account profile password change two-factor authentication mfa totp authenticator recovery codes self-service"><p class="eyebrow">My Account</p><h2>Managing your own profile, password, and two-factor authentication</h2><p>My Account is available to every role — Administrator, Standard User, and Viewer alike — and only ever affects your own account. It sits in the sidebar next to Administration and Documentation.</p><h3>Profile</h3><p>Shows your display name, username, and role. These are read-only here; an administrator changes them from Administration → Users.</p><h3>Changing your password</h3><p>Enter your current password once, then your new password twice. This works for every role — previously, only an administrator could change a user’s password (Administration → Users → Reset password), which meant every routine password change had to go through an admin. My Account closes that gap for everyone’s own account.</p><h3>Two-factor authentication (2FA)</h3><p>Optional and off by default for every account. When enabled, signing in requires your password plus a 6-digit code from an authenticator app (or a recovery code), using the standard TOTP algorithm (RFC 6238) — any authenticator app works, not a Site Gateway-specific one.</p><h3>Enabling 2FA</h3><ol><li>Choose Enable two-factor authentication.</li><li>Scan the QR code with your authenticator app, or enter the shown key manually.</li><li>Enter the 6-digit code it generates to confirm setup.</li><li>Save the 10 recovery codes shown immediately afterward — each works once, and this is the only time they’re shown in full.</li></ol><h3>Signing in with 2FA enabled</h3><p>After your username and password are accepted, you’re prompted for a code. Enter the current 6-digit code from your authenticator app, or one of your unused recovery codes if you don’t have the app available. A wrong code shows an inline error without sending you back to the username/password screen.</p><h3>Disabling 2FA, or regenerating recovery codes</h3><p>Both require re-entering your current password as confirmation. Regenerating recovery codes immediately invalidates the previous set.</p><p>An administrator resetting your password does not disable your 2FA — you’ll still need your authenticator app or a recovery code at your next sign-in. Only you can turn off your own 2FA, from My Account.</p></article><article data-doc="gateway defaults default site welcome themed 404 abort redirect custom html unknown hostnames live preview real time"><p class="eyebrow">Administration</p><h2>Gateway Defaults: handling unknown addresses</h2><p>Controls what happens when a visitor reaches Site Gateway on HTTP using a hostname that isn’t configured.

It only shows something for the modes that actually serve a page (<em>Themed route-not-found page</em>, <em>Gateway ready page</em>, and <em>Custom HTML</em>); for <em>No response</em> and <em>Redirect elsewhere</em>, the pane explains why there’s nothing to preview — those modes close the connection or send the visitor elsewhere before any page is ever shown.

The pattern currently checks the path for: path traversal sequences (<code>../</code> or <code>..\</code>); direct requests for <code>/etc/passwd</code>; WordPress probing (<code>/wp-login.php</code>, <code>/wp-admin/</code>, <code>/xmlrpc.php</code>); exposed config/VCS paths (<code>/.env</code>, <code>/.git/</code>, <code>/.aws/</code>); exposed PHPUnit test endpoints (<code>/vendor/phpunit</code>, <code>/phpunit/</code>); the literal strings <code>eval(</code> and <code>base64_decode(</code>; a SQL <code>UNION SELECT</code> sequence; and <code>&lt;script</code>. Matching is case-insensitive. <strong>Important:</strong> this only inspects the URL path — it does not inspect the query string, request body, cookies, or headers, so a SQL-injection or XSS payload sent as a query parameter (e.g. <code>?id=1 UNION SELECT...</code>) is not caught by this toggle. This is a small, fixed, path-only ruleset, not a full web application firewall — it will not catch every attack, cannot currently be extended with custom patterns, and should not replace keeping the upstream application itself patched.</li><li><strong>Custom Locations:</strong> send specific paths to a different upstream. One per line: <code>/api/* | http://192.168.1.20:3001 | strip</code> or <code>preserve</code> — <em>strip</em> removes the matched prefix before forwarding, <em>preserve</em> keeps it.

Once Upstream pool has any entries, Caddy uses only those targets — the single Forward-to address above is not automatically added to the pool alongside them, so include it as one of the pool lines too if it should keep receiving traffic.</li><li><strong>Load balancing:</strong> only takes effect once Upstream pool has 2 or more entries — Forward to is never counted toward this, per the note above. <em>Random</em> (Caddy’s own default) picks a target at random per request; <em>Round Robin</em> rotates through targets evenly; <em>Least Connections</em> sends each request to whichever target currently has the fewest active requests; <em>IP Hash</em> sends a given client’s requests to the same target each time (sticky sessions), useful for applications that keep session state on one backend. This only affects which upstream Caddy sends a request to — it does not change the separate Health-check settings below, which only drive Site Gateway’s own dashboard status.</li><h3>How to verify a change</h3><p>Save one setting at a time, watch the card’s upstream status line, check Access Logs, and compare against a direct request to the application.

Use it for services that speak their own protocol directly over a port: SSH, a Minecraft or other game server, a VPN endpoint, or any similar TCP/UDP service.</p><h3>The one prerequisite: publish the port first</h3><p>Streaming Hosts listen for connections from <em>inside</em> the Site Gateway container itself — they are not routed through Caddy the way domains are. That means the incoming port must already be published on the container (added to your <code>docker-compose.yaml</code> or Unraid port mappings, with the container recreated) <strong>before</strong> you create the matching Streaming Host in the UI, or nothing outside the container will ever reach it.</p><h3>Example docker-compose port mapping</h3><p>To forward SSH (22) and a Minecraft server (25565):</p><p><code>ports:<br>&nbsp;&nbsp;- "22:22/tcp"<br>&nbsp;&nbsp;- "25565:25565/tcp"</code></p><h3>Creating a Streaming Host</h3><ul><li><strong>Name.</strong></li><li><strong>Incoming port:</strong> 1–65535. Cannot be the admin port, 80, 443, a port already inside the Hosted Sites port range, or a port already used by another Streaming Host.</li><li><strong>Forward to:</strong> a plain <code>host:port</code> address, e.g. <code>192.168.1.20:25565</code>. No <code>http://</code> — this is a raw socket forward, not a web address.</li><li><strong>TCP</strong> / <strong>UDP:</strong> enable one or both. At least one must stay checked.</li><li><strong>Monitor this target:</strong> runs a TCP reachability probe against the forward address every check cycle, even for UDP-only streams (UDP itself has no reliable way to “ping” a service).</li></ul></article><article data-doc="streaming hosts how it works tcp relay udp relay session multiplex health probe examples"><p class="eyebrow">Streaming Hosts</p><h2>How the forwarding actually works</h2><p><strong>TCP</strong> is a full one-to-one relay: every inbound connection gets its own fresh outbound connection to the forward target, and the two are piped together in both directions. Closing or erroring either side tears down the other.</p><p><strong>UDP</strong> is connectionless, so Site Gateway multiplexes many remote clients over one listening port by tracking a short-lived “session” per unique client address, each with its own outbound socket to the forward target. An idle session is cleaned up automatically after about a minute of inactivity.</p><h3>Health monitoring</h3><p>The monitor always performs a plain TCP reachability check against the forward address, with a 4-second timeout — this confirms the target host and port are reachable, not that the specific game or service protocol is fully healthy. Disabling monitoring shows the card as “Monitoring paused” rather than unreachable.</p><h3>Practical examples</h3><ul><li><strong>SSH:</strong> incoming port <code>2222</code>, forward to <code>192.168.1.30:22</code>, TCP only.</li><li><strong>Minecraft:</strong> incoming port <code>25565</code>, forward to <code>192.168.1.20:25565</code>, TCP (and UDP if the specific server/mod needs it — vanilla Minecraft is TCP-only).</li></ul><h3>Editing a Streaming Host</h3><p>Changing the port, target, or protocol checkboxes restarts the listener immediately to apply the change; toggling Enable/Disable does the same.</p></article><article data-doc="certificates overview automatic https prerequisites dns ports check now readiness"><p class="eyebrow">Certificates</p><h2>Overview: automatic HTTPS prerequisites</h2><p>For Automatic HTTPS to succeed, a domain must resolve to your public address, inbound ports 80 and 443 must reach Site Gateway, and no other service (including another reverse proxy) can already own those ports on this host.</p><h3>Domain readiness checks</h3><ul><li><strong>DNS:</strong> confirms the domain actually resolves, and to what address.</li><li><strong>HTTP / HTTPS:</strong> confirms Caddy itself is listening on ports 80/443 inside the container — this does not by itself prove the internet can reach you, only that the gateway is ready to answer if it can.</li><li><strong>TLS:</strong> reflects the certificate status for that domain (healthy, renewing soon, critical, expired, or “Waiting for Caddy,” meaning issuance hasn’t completed yet — not that anything is broken).</li><li><strong>Upstream</strong> (Proxy Hosts only): the latest health-check result for that route.</li></ul><h3>Check now</h3><p>Forces an immediate re-check of every certificate, domain readiness result, and health probe instead of waiting for the periodic background check.</p><h3>Novice workflow</h3><p>Confirm DNS, forward ports 80 and 443, stop any competing proxy, then run Check now.

Delete and Change icon live under the card’s “•••” menu, matching Hosted Sites and Proxy Hosts; role, password reset, and archive stay as visible buttons. You cannot disable, archive, delete, or change the role of your own account — another administrator has to do that — and Site Gateway always keeps at least one active Administrator, refusing any action that would leave zero. Resetting a user’s password here does not disable their two-factor authentication if they have it enabled — see My Account for how 2FA works. There is currently no administrator-side way to turn off another user’s 2FA; only that user can, from their own My Account page.</p><h3>Groups</h3><p>A Group is simply a named set of users. Its only purpose is authentication: assign a Group to an Access List so its members can log in with their own Site Gateway credentials instead of a separate Access-List-only login.</p><p>Every Group has its own enable/disable toggle, separate from deleting it. <strong>Disabling a Group immediately stops it from granting access through any Access List it’s assigned to</strong> — the assignment itself is untouched and still shows as assigned, but its members can no longer authenticate through it until the Group is re-enabled. This is a common surprise: disabling a Group is not the same as archiving it for later cleanup, it has an immediate access-control effect. If the Group is currently assigned to at least one enabled Access List, disabling it now asks for confirmation first, naming exactly which Access List(s) will stop authenticating that Group’s members — the same pattern already used when disabling an Access List that protects active hosts.</p><h3>Audit history</h3><p>Administration includes an Audit log — a searchable, filterable, immutable record of who did what, filterable by outcome (success/failed) and free-text search across the user, action, and target. Audit entries can’t be edited or deleted.</p></article><article data-doc="my account profile password change two-factor authentication mfa totp authenticator recovery codes self-service"><p class="eyebrow">My Account</p><h2>Managing your own profile, password, and two-factor authentication</h2><p>My Account is available to every role — Administrator, Standard User, and Viewer alike — and only ever affects your own account.

Regenerating recovery codes immediately invalidates the previous set.</p><p>An administrator resetting your password does not disable your 2FA — you’ll still need your authenticator app or a recovery code at your next sign-in.

This only matters for a tab left open across a deploy; closing and reopening the tab, or signing in fresh, always loads the current version automatically.</p></article><article data-doc="icons change icon picker search catalog custom upload url fallback initials"><p class="eyebrow">Icons</p><h2>Changing a card’s icon</h2><p>Every Hosted Site, Proxy Host, Redirect Host, Streaming Host, Access List, Group, and User can have its own icon.

Then check Certificates and Logs → Gateway Events for the specific rejection reason. Site Gateway cannot request a public certificate while another gateway is receiving the ACME challenge on its behalf.</p><h3>A route rejected its configuration</h3><p>Check the error shown on save — it names the specific problem (duplicate address, invalid upstream, malformed custom configuration, certificate/TLS issue) rather than a generic failure, and the previous working configuration stays active while you fix it.</p><h3>A Streaming Host isn’t reachable from outside</h3><p>This is almost always the port not being published on the container yet — see Streaming Hosts → Overview for the docker-compose/Unraid port mapping requirement.</p><h3>A user is locked out after enabling two-factor authentication</h3><p>If they still have an unused recovery code, they can sign in with it in place of the 6-digit code. If not, there is currently no administrator-side way to disable another user’s 2FA — only the affected user can turn it off, from My Account, which itself requires signing in first. Keep this in mind before encouraging 2FA adoption broadly.</p></article></div></div><p id="doc-empty" class="quiet-state hidden">No guide matched that search.</p></section>
