Use Static NAT

ip nat inside source static tcp 55541 interface Ethernet1 55541

Replace with the actual IP Address of the pc you want the traffic forwarded to. Replace Ethernet1 with the interface on the 1800 that is configured with "ip nat outside"

How about using port 8080 of the cisco router and forwarding it to port 80

by muyjr In reply to Use Static NAT

I want to open port 8080 of the cisco 1800 Router but I want to link it to port 80 on the machine behind.

Here is a cisco document that explains it:**86a0080094e77.shtml#topic8

Note that in their example they are forwarding port 80 on the router interface to port 8080 on the computer so it is opposite of what you want to do, so you need to use ip nat inside source static tcp 80 interface Ethernet1 8080
Also, if you have any access-lists applied to your inside and/or outside interfaces, you need to add statements to allow that traffic.
