I'm definitely not a networking guru, but I'll take a shot at it. First of all, if you haven't already, take a look at the recently updated IP Masq HOWTO found at the link below. It explains most everything you need to know including what's needed for 2.2.X vs 2.0.X kernels. http://www.tor.shaw.wave.ca/~ambrose/ipmasq-HOWTO.html#toc3 As a simple example, here's my /etc/init.d/network for the gateway machine on a 2 computer home network. I'm using the plip device (parallel port cable) instead of network cards, but it's the same idea. I'm using kernel 2.2.3 now. -------------------------------------------------------------------- #! /bin/sh ifconfig lo 127.0.0.1 route add -net 127.0.0.0 netmask 255.0.0.0 dev lo ifconfig plip0 192.168.1.1 pointopoint 192.168.1.2 up route add -net 192.168.1.0 netmask 255.255.255.0 dev plip0 echo "1" > /proc/sys/net/ipv4/ip_forward ipchains -P forward DENY ipchains -A forward -s 192.168.1.0/24 -j MASQ # these were used with kernels 2.0.XX instead of ipchains # ipfwadm -F -p deny # ipfwadm -F -a m -S 192.168.1.0/24 -D 0.0.0.0/0 --------------------------------------------------------------------- You also have to set the default route on the machine(s) that will be using the gateway machine to access the Internet or whatever. Here's how I have the /etc/init.d/network file set up on my other machine: ------------------------------------------------------------------- #! /bin/sh ifconfig lo 127.0.0.1 route add -net 127.0.0.0 netmask 255.0.0.0 dev lo ifconfig plip0 192.168.1.2 pointopoint 192.168.1.1 up route add -net 192.168.1.0 netmask 255.255.255.0 dev plip0 route add default gw 192.168.1.1 -------------------------------------------------------------------- Tom -- Try Debian GNU/Linux - it's free, it's open source, and it rocks http://www.debian.org
