Do you mean to and from the router (eg copying new IOS) or do you mean NATing through the router?

OK- Let's assume the server is running on port 21, but you want users to connect to 2121 for FTP. You'll need to create a NAT translation.

ip nat inside source static tcp 192.168.0.1 21 interface [public ip] 2121

Don't forget to allow TCP 2121 in your ACL.

Hope that helps.
