II> the other machines with Internet. I did it with the following II> commands: II> iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE echo 1 >> /proc/sys/net/ipv4/ip_forward I've done exactly what you did. Both of those firewall commands are a part of Monmotha's IP Tables Firewall. Google on Monmotha. The neat thing about using a firewall script is that you can also do inbound port mapping....such as sending a particular port to a particular machine. Along these lines I use Radmin to control my win2K box from afar - Inbound port whatever is automatically port forwarded to the win2k macine which is privately addressed and lives behind the firewall. So if you're gonna do anything like this...then just get the firewall script which automatically does both of the commands you pointed out - and so much more.
