Actually, that's the way I started with linux only I didn't use 3Com
cards, I used realtek cheapo ISA (which is a Novell 2000 clone) and I
had to learn about the double config on the first card (for the second
card) the hard way.
3Com is fine - Novell clone cards are fine AS LONG AS ...
1. You have a DOS boot disk
2. You have the proper configuration software to configure them because
they are jumperless and you have to use software to configure the IRQ &
Base Address.
3. Write this information down - a reboot / a linux install and the dog
licking itself endlessly will make you forget what was so clear 5
minutes ago. Maybe the CMS Syndrom is a personal issue.
4. Make it easy on yourself, install linuxconf even though it is
deprecated on Redhat 7.1 - DO NOT BOOT TO XWINDOWS. Use the
configuration information that you set up in step 2 to configure the
first card.
In fact - as a router, Xwindows has no place but when you install Redhat
7.1 server - you get no configuration tools at all - hence my
recommendation to install linuxconf. Actually, I would recommend that
you use webmin <
http://webadmin.sourceforge.net> but that is a bit tough
to use if you haven't x-windows and have not gotten networking up and
running.
Lastly, I would suggest that you use something earlier than RedHat 7.1
on this machine (6.2 or 7.0 which have the 2.2.x kernel) and not fool
with iptables yet (or the crippled ipchains on 2.4 kernels) and get

for MASQ'ing the internal lan.
