As its name implies, Port Forwarding performs a forwarding, allowing a particular port to be determined for specific IP addresses on a LAN. This makes it possible, for example, to connect to another appliance or service through a private network, regardless of whether the appliance is behind a router.

Port Forwarding is made up of packet filter rules with the option of address translation, making it possible to modify the destination address of client machines. Through its resources, it is possible to route traffic between the buses and configure DNAT masking, the latter being especially useful in redirecting ports.


Port Forwarding rules are loaded from top to bottom, so the rules at the top of the table have priority over the ones below (being possible until they overlap the settings of the bottom rules).


To open the screen, click on the “Port Forwarding” tab.
