Port forwarding... kinda...
A quick explanation of my LAN setup: I have a hardware router (192.168.1.1) with two PCs (192.168.1.6 = gentoo) and (192.168.1.5 = WinXP).
I have set everything up so that Gentoo/.1.6 is sitting on the DMZ and runs apache/squid/webmin/etc using an iptables firewall.
WinXP/.1.5 is merely a workstation and essentially has no "knowledge" of the linux box in any way.
However, now i want to run a daemon on the WinXP/.1.5 box (lets say port 5678), but as the hardware router is set up to keep Gentoo/.1.6 on the DMZ i want to use Gentoo/.1.6 to do the port forwarding.
So how can i make all traffic apearing on port 5678 of the Gentoo/.1.6 box "forward onto" the WinXP/.1.5 box using iptables?
Thankyou a lot,
