Your English wasn't that clear, but I think I understand 
These are the rules I use to enable port forwarding:
| Code: | iptables -t nat -A PREROUTING -p tcp -i eth0 --dport 22 -j DNAT --to 192.168.0.x:22
iptables -A FORWARD -p tcp -i eth0 -d 192.168.0.x --dport 22 -j ACCEPT |
eth0 is connected to the internet, replace the x with the ip of the computer where you want to redirect to.

I'm really not understanding this  Is the router a linux server? Or is it such a modem which delivers two ip's to the connected computers ? If I'm guessing right this time, you want to redirect the public (internet) port 22 on your computer to the public port 22 of the other computer? Is this through a second ethernet adapter or through the same? Your scheme isn't very clear
