Port forwarding is a networking technique that allows you to redirect incoming traffic from one port to another on your network. This can be useful for a variety of purposes, such as hosting a web server or running a game server behind a firewall.
To set up port forwarding on your pfSense firewall, you will need to create a new firewall rule. In the “Firewall” menu, click on the “Rules” tab and then click on the “Add” button. In the “Action” drop-down menu, select “Pass”. In the “Interface” drop-down menu, select the interface that you want to receive the incoming traffic on. In the “Protocol” drop-down menu, select the protocol that you want to forward. In the “Source” field, enter the IP address or range of IP addresses that you want to allow traffic from. In the “Destination” field, enter the IP address of the computer that you want to forward the traffic to. In the “Port” field, enter the port that you want to forward the traffic to. Click on the “Save” button to create the new firewall rule.
