Ok the subject is a little misleading, what I am looking to do is have an internet connection on one ethernet card, an external network on another card and the internal network on yet another card.
----------------------
| | --------- External Network
Internal---------| Linux Box |
| | --------- Internet
----------------------
The external network has 2 set address ranges lets call them 172.x.x.x and 173.x.x.x
I want the traffic on those to ranges to go via the External Network NIC and all other to go via the Internet
So far researching on how to do this it looks link I need to use iptables and do some advanced routing.
Currently I am experimenting with slackware 10.1 as the base, but if another dist is better I will get it.
Can anyone point me in the right direction or give me some pointers/help?
Thanks, From Kim
