I have a client who has a 2611 Router with IOS 12.0. I have looked all over Cisco's web site and cant find how to configure it for Port Forwading. I just need to set up a simply redirection of a port to a internal IP.
The topic of this forum is General Security however there are a number of professionals online who may be able to assist you. We are always considering additional forums for such topics and I will make a note of your post.
From your brief description, it is difficult to tell exactly what you are wanting to accomplish. A specific example would be helpful. Perhaps you need to use NAT here - you would assign an address such as 192.168.1.1 to the ethernet0 interface, but when packets hit that address on port 80 they are then sent on/forwarded to another pc. In this fashion, you can have multiple pc's using the same public ip address, just assigned to different ports e.g. 80 for the http server, 21 for the ftp server, etc. If this is what you are shooting for I can dish out some good samples, but specifics would help.
