The firewall in front of pc1 is a Stateful firewall, isn't it? Probably iptables. The problem is that your firewall will let packets trough only if it knows those packets belong to a connection. If you start sending packets from pc1 then packets from pc2 are supposed to be from the same 'connection' (ok, UDP has no connections, but just to ilustrate my example :-) So when time passes, and there's no traffic, if pc2 tries to send anything to pc1, the firewall won't associate those packets with anything 'going on' and it won't let them pass. I hope I made myself clear, I'm in a hurry now! :-) Excuse any grammar/spell/networking concepts in this mail O:-) Regards -- Alberto Gonzalez Iniesta | They that give up essential liberty agi@xxxxxx | to obtain a little temporary safety Encrypted mail preferred | deserve neither liberty nor safety.
