Many different network architectures and device require port forwarding rules to operate. These rules are simple to implement as long as you know the terminology used by the router. This is detailed below including step by steps directions.
1. Login to the Local Configuration Webapp (need help?).
2. After you login to the Web App, click Firewall tab, and select Port Mapping in the dropdown menu.
3. This will place you on the screen where you write your rules. Click the Add button to add additional lines for additional rules, and click apply when you are ready to save then. See the descriptions for each field of the rule.
1) Proto: This is asking what protocol the traffic that you need to forward is using. You have the option of UDP, TCP or both. If you are unsure of what the right answer using both is normally safe.
2) Source: This allows you to define what source IP the traffic you need to forward is coming from. Note that you may define a field of addresses by using the correct CIDR value. If you want to forward all traffic type 0.0.0.0/0
3) Service Port: This is the incoming port that you want to forward.
4) Internal address: This would be the address that the router is assigning to the device that you want to forward traffic to i.e. a server. If you are sending one port to a different port on the router use 192.168.2.1
5) Internal Port: This is the port on the device in your network that you want this rule forwarding traffic to.
6) Log: Check this if you want each forward of traffic to leave a stamp in the log files of the router. This is normally only done for troubleshooting purposes.
7) External Interface: This allows you to specify if only a specific WAN interface should use this rule. Leaving this field blank will make it apply to all WAN interfaces.
8) External Address: This allows you to forward a packet to an address outside of the router.
9) Description: This allows you to label each rule that you write for ease of management.
