Port Forwarding in a Cisco router is the same as Static Nat.

To forward your services you would type in the following

ip nat inside source static <protocol> <inside IP address> <inside port #> <Inside Global IP or Interface> <External Portx>

Example for Remote Desktop Connection
ip nat inside source static tcp 172.16.1.126 3389 fastethernet 0/1 3389

The first IP is the server inside your network. The FastEthernet 0/1 would be an example of the port you have connect to your DSL Modem , Cable Modem, or whatever you have it hooked into to get Internet.

You would do similar configurations for each of your needed applications to be forwarded.

Let me know if you need more help with this

I am sorry, I am having trouble understanding what I just read. Maybe you can explain what exactly you meant by these words? I have a Linksys Cisco router, as well as a port-forwarding problem. Thanks in advance!
