I want to use my linux box as a gateway between a LAN and
the ethernet backbone:
=======10baseT Ethernet backbone=====University Gateway===>

|________| |________| |________|
Linux box 2 Linux box 3 Linux box 4
I have 2 IP addresses for linux box 1, one for each ethernet
card. I also have an IP address for each of the linux boxes
on the LAN and don't need to do masquerading. The University gateway IP is IP0.
Question 1: What deamons do I need to run on linux box 1,

Question 2: what are the correct command line arguments for
route and ifconfig on each linux box to make the system work? I don't need a firewall, just want to use Linux box 1
as a router/gateway for the Linux boxen 2-4. I basically want to route all TCP/IP traffic for the box 2-4 through a
Question 3: What features do I need to enable in the kernel to make this work?
