I have 2 Macs at home that work fine with port forwarding at home, just not at the same time. My router has Port 32 forwarded to Port 22 to my MiniG4's fixed IP and it doesn't work (for FTP access). Though when I change to Port 22 to 22 it works fine. The problem is that my iBook has Port 22 assigned to it, so I can't FTP to both computers at the same time (or when I need one). Using SSH I forward port 31 to 21 on my mini and that works fine. And forward 21 to 21 for my iBook and that works fine. Why can't I port forward port 32 to 22? I really hope that makes sense to you guys. EDIT: Both machines all current OS X (10.4.10).
