Hey.. I have Ipchains setup with the strong ruleset, and masqing. I want to host Delta Force Land Warrior games on an internal machine. I will be using 3 ports (udp only) for this until I determine what of those I do not require. :)
I add an ipmasqadm portfw line after my ipchains for each port. This alone does not work, so I Accept for each port in input, output, and forward rules. This also does not work. So I open up the outgoing for each port ALL 3 rules. This works. Why do I need to open the outgoing, shouldn't my MASQ line cover that? A incoming connection goes through Input, Forward, then Output, correct? What would be the route for outgoing, the same? ps... And what is DMZ? :P
