Our ISP has provided us with a public IP.

I have connected their Modem of a Cisco router 1710, and the second port (FastEthernet) to our internal network.

I have Natted the public IP to one of the PCs inside our network, so that the outside world can reach the PC.

Is it possible that a connection on a specific port on the public IP addr. is natted to a second PC.


http://'IP Address':8080 goes to PC1

http://'IP Address':8000 goes to PC2

How to configure the router?
