Configure Port Router Forwarding

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 can edit or delete rules from the table. Use the following steps to enable port forwarding and create forwarding rules.

Select the user name of the router for which you want to enable port forwarding.
On the Configure tab, go to Port Forwarding.
Enable Port Forwarding.
Select the plus sign to add a new port forwarding rule.
Enter a description of how this rule will be used (optional).
Select a number for the outside port from the range of 1025-65535 (reserved ports cannot be used).
Select a number for the local port from the range of 1-65535.
Select TCP, UDP, or both from the protocol drop-down list.
Select a host IP address for the internal device from the drop-down list, or select the plus sign to add a new address.
Select Add.
When you are finished adding rules, select Save.
