7.3 Application Port Forwarding
Setup > VPN Settings > SSL VPN Server > Port Forwarding
Port forwarding allows remote SSL users to access specified network applications or
services after they login to the User Portal and launch the Port Forwarding service.
Traffic from the remote user to the router is detected and re-routed based on
configured port forwarding rules.
Internal host servers or TCP applications must be specified as being made accessible
to remote users. Allowing access to a LAN server requires entering the local server IP
address and TCP port number of the application to be tunneled. The table below lists
some common applications and corresponding TCP port numbers:
