Sorry, Ze'ev, but it looks like Mack wants an ethernet bridge, not a
router.
The good news is that kernel 2.0.0 supports ethernet bridging. I
don't know if it works yet, though. Here's what it says in
/usr/src/linux/Documentation/Configure.help:
Bridging (EXPERIMENTAL)
CONFIG_BRIDGE
If you say Y here, then your Linux box will be able to act as an
ethernet bridge, which means that the different ethernet segments it
is connected to will appear as one ethernet to the
participants. Several such bridges can work together to create even
larger networks of ethernets using the IEEE802.1 spanning tree
algorithm. As this is a standard, Linux bridges will interwork
properly with other third party bridge products. In order to use
this, you'll need the bridge configuration tools available via ftp
(user: anonymous) from shadow.cabi.net. Note that if your box acts
as a bridge, it probably contains several ethernet devices, but the
kernel is not able to recognize more than one at boot time without
help; for details read the Multiple-Ethernet-mini-HOWTO, available
via ftp (user: anonymous) in
sunsite.unc.edu:/pub/Linux/docs/HOWTO/mini. The Bridging code is
still in test. If unsure, say N.
Good luck, and tell me how it works...
