I work for an ISP and we have decided to use linux as a temporary =
gateway for a few machines. We have installed 2 ethernet cards in this =
machine, and both work properly. I have eth0 connected to the =
internet, and eth1 goes into the hub, for the internal network. I can =
ping internally all machines, but packets do not get forwarded to eth0 =
(the internet.) I am running 2.0.36 kernel right now, but i am =
upgrading to 2.2 as we speak. I know this is a routing problem, =
getting packets from eth1 to forward to eth0 and out to the net, but i =
cannot figure it out for the life of me. I have used IP masquerading =
with no problem, but we need real routable IP's. Any help would be =
appreciated, thank you.
