masquerading and port range forwarding to internal host (with a private address)

I'm running 8.2 and so far i've ben able to use /etc/sysconfig/SuSEfirewall2
to do all the firewalling i wanted, but now i want to forward a whole port
range to one of the host on the internal network, and the only option
(FW_FORWARD) takes 2 public IP addies as arguments (from what i read about
it on the list archive anyway). Problem is, most of the messages i've read
are quite old (2000-2001) and address 2.2 kernel issues.
i run iptables (came with 2.4 kernel, and it did what i wanted it to), so
i'm asking here in a fresh message.

so, in short, if i want to forward ports 12030-12100 to a host on my
internal network, can i do it with /etc/sysconfig/SuSEfirewall2 or do i have
to input an iptables rule myself?
could anyone help building said rule?

thanks a lot
