[lug] network card problem

[Nate Duehr]

You can use any box with multiple NIC's in it as a standalone router if you
configure proxy arp and IP forwarding without firewall features... :-)  Or you
use static routes to get to the "router" machine.  In his case, I assume the
default router for the 10.x.x.x machine is the linux machine.

Hmmm... back in the day these were called "gateways"... now I'm feeling old.
:-)  And I'm not really....

But in this person's case, I think you're right... he's going to want
firewalling features "turned on" because he's going to need to NAT that
10.x.x.x address to something useful for his network on the other side of the
linux box.

There's simply not enough information in the original e-mail to really know.
It's all rather simple when the network is known to you and the underlying
protocols are understood.
