Hi Adrian, The easiest way is to give your Debian box a static ip on the "inward" NIC, then set the gateway in the Windoze boxes to that IP. Then you need to use iptables for the actual NAT-ing, here is a very simple recipe that should make it work. Keep in mind this is not a complete firewall, this is just the bit you need to enable sharing the Internet connection: # modprobe iptable_nat # iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # echo "1" > /proc/sys/net/ipv4/ip_forward This should work exactly as it's written, except make sure you specify the correct eth0 or eth1, whichever one is the "inward" card. -- ~~~~~~~~~~~~~~~~~~~~~~~~~ Carla Schroder www.tuxcomputing.com this message brought to you by Libranet 2.8 and Kmail ~~~~~~~~~~~~~~~~~~~~~~~~~ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
