I have a fedora core linux box (fc6) which acts like a DHCP server.
INTERNET ----- LINUX BOX ----- WINXP
The problem im having is forwarding a port to my winxp machine.
for this i know u have to use iptables so this is the rule i have written
iptables -I FORWARD -p tcp -d 192.168.0.101 --dport 6762 -j ACCEPT
where 192.168.0.101 is the ip address of the windows XP computer and 6762 is the port i want to forward
