4.9.3 Port Forwarding
Click “NAT” —> ”Port Forwarding.”
Port Forwarding functions the same way as Internal Server, but it allows entering
ranges of ports instead of single ports only. It also does not limit you to pre-defined
services. Instead, you can control the entire TCP/IP port range.
Setup Method:
Rule Name: Enter a name which best describes the function of this rule.
Protocol: Port transfer protocol. There are two choices: TCP and UDP.
External Port Range: Port range that is open to the outside.
Internal PC IP Address: Where the router forwards traffic to the local computer.
Internal Port Range: Internal PC Port Range (in most cases this is identical to the
External Port Range).
Example: You wish to run a “Silent Hunter III” server behind the router and want
Internet users to be able to access the server remotely. Silent Hunter III requires
ports (http://www.portforward.com/english/applications/port_forwarding/
SilentHunterIII/SilentHunterIIIindex.htm) 17997–18003 for both TCP and UDP to be
opened and forwarded. Your local Silent Hunter Server has the IP address
192.168.0.150.
Rule Name: SHIII TCP
Protocol: TCP
