outbound port 80 redirect to specific destination address

I have a cisco 2600 router with a connection to my internet and LAN. I would like to connect to my friend's server out the internet. His ISP does not allow incoming port 25. He has set the server to accept port

2525 connections. I need help to clear the cobwebs with my cisco commands. I would like it so that if my destination address is my friend's server then change the tcp port to 2525.

i know from a pix firewall, i can use static(inside, outside) 2525 25 to change tcp ports. Is there an equivalent for an IOS router? I don't want all port

25 traffic redirected, just if the destination is my friend's server. I'm sure there's an access list for matching involved here.

Thanks for any feedback.
