UPnP IGN would help for Xbox or PC Gaming from behind the firewall. MiniUPnP can provide this functionality if integrated into the LinuxMCE firewall. I am not in a position to preform this, but I thought someone might take an interest.http://miniupnp.free.fr/
I dont understand...you can already setup your ps3 or xbox from behind the lmce firewall. Why would we need this? What additional functions would it provide?
