Susefirewall 2

Hi I wasted a lot time trying to understand how the Susefirewall works but i still having one problem that i need to solve with some help of someone. I made the server responding ports 22 53 80 with the subnet having access to internet through masquerading. ok but now i need the port 22 go to other server in my subnet 192.168.0.2 i had tried to use FW_FORWARD_MASQ= "0/0,192.168.0.2,tcp,22" and "200.174.40.130/26,192.168.0.2,tcp,22" but in this way it doesnt work. What is wrong? if it works out fine i will try to put the mailserver into the subnet is it possible too? thanks for all Joni Hoppen
