The exact URL depends on your specific Firebox configuration :
: If other features like the Access Portal or Branch Office VPN (BOVPN) over TLS are active, they may share the same port (usually 443), with specific precedence rules governing which feature "owns" the port.
: Users enter the URL in a web browser and authenticate using their Firebox-DB, RADIUS, or AuthPoint (MFA) credentials.
If the VPN is configured on a non-standard port (e.g., 444), you must include it: https://[Firebox IP address or FQDN]:444/sslvpn.html
: If the portal doesn't load, ensure the WatchGuard SSLVPN policy is enabled and that the specified port is not blocked by an ISP or upstream router.
Administrators define the that these URLs point to within the Fireware Web UI under VPN > Mobile VPN > SSL .
