Ok all I want to do is set my MAIN computer to be the DMZ host on the network...

I have a cable modem with my private IP's being on the 192.168.1.0/24 network

I'm using SLAKWARE8, 2.4.5 Kernal.
The router box is a k62 450 with 64MB of ram.

I have NAT enabled via the commandline:

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE;
echo 1 > /proc/sys/net/ipv4/ip_forward

I can access browse and play games just fine however I want to run a few game servers or have the freedom to pop up and ftp when ever... I don't want only a few ports, I want them all to be forwarded to my machine...

I have not a clue on how to setup port fowarding in linux to do this...

Any help would be greatly appreciated...
Thanks,
