I have a question on this setup. Which machine is doing the the masq? It
seems to me that if all the machines are connected to the same hub as the
modem, arn't all machines 'exposed' to the internet through the dsl
modem? What is your default route? The reason for the second nic (my
understanding) is that all machines must connect through a single masq
machine, so all traffic flows to nic_1 gets masq'd then goes to the
internet
through nic_2.
The 486 that connects to the internet also does the masquearading. All
traffic flow to eth0, and gets masq'd, but then goes to the internet
through ppp0, which is in fact a ppp connection using pptp (which talks to
the modem via the very same eth0). To the rest of the network the modem is
just 10.0.0.138. Only the 486 is 'exposed'. I hope this clears things up.
If not, I'll explain more.
Matijs.
