This is unlikely but it ought to get eliminated from consideration. sockstat -4l will tell you what is listening to which ports. Next time it gets "closed" take a quick look at this and ensure the game server is actually still listening to this port. If it is not it is most likely a configuration detail relevant to the game server. Second, this sounds a lot like a NAT session timing out from inactivity. If such a situation should be the case it is possible to design a rule specific so the ports' traffic can bypass NAT and run "straight-through". If the first thingy from above gets eliminated this is where I'd look next. As to exactly how you would go about tailoring such a rule would depend upon the syntax of whichever firewall you are using. -Mike
