I need to set packetfiltering on a debian linux firewall to enable a network game. Necessary firewall settings are descibed here: http://support.microsoft.com/default.aspx?scid=KB;en-us;q240429 The system has client computers with 192.168.1.1x fix local IP addresses (no DHCP), and a gateway with both internal (192.168.1.1) and external (both fixed) IP adresses, w/ two network card of course (eth0 - external, eth1 - internal). Can anyone give me a hint what settings are necessary? Thanks in advance, Eugenio
