When enabled, port forwarding allows a router to open certain ports to incoming traffic from specified IP addresses. Port forwarding is helpful when you have a server behind your router that needs a port exposed to the Internet, such as an HTTP server that needs to be accessible to people outside the VPN, Branch, or HQ network. For each port, a port forwarding rule applies. You can have up to 128 port rules. You an edit or delete rules from the table. Use the following steps to enable port forwarding and create forwarding rules.
