I'm already running 2.4, and iptables (said so in my message).
>From what i gater from your and Barry's messages, i already had it figured
out, but the online documentation had me confused, so i was looking at the
wrong place.
I should have just sticked to the #comments in the file and then mimmicked
the syntax used in other options for the port ranges. thanks for clearing
that one out barry, very much appreciated :D
I'll try that way and report back

Hello Ben,
You must update your kernel 2.2.1 to 2.4.x if you will use iptables support.
You can update your kernel with yast. Very easy and fast solution.
Definitely you must type FW_ROUTE="yes" and
and you must type
FW_FORWARD="source_ip,dest_ip,protocol,dest_port" if not use masqueraded
if use masqueraded network you must use FW_FORWARD_MASQ expression
good lucks.
