Firewall + 3 NICS on DSL and T1
I would like to setup one firewall to handle both my DSL line and my T1 line.
All of the incoming and outgoing e-mail goes through the DSL line.
All of the web traffic passes through the T1 line.
Right now, my DNS server goes through the DSL line but in the future I'd like the DNS to be able to accept queries on both the DSL and the T1 networks.
I am thinking that I'd need 3 network interfaces on my firewall. 1 for the LAN, 1 for the DSL and 1 for the T1.
Does anyone have any pointers on setting up a Linux machine with 3+ NICS?
I currently run a pair of Linux firewalls (ipchains) with 2 NICS. I setup 1 multihomed Linux machine to handle the DSL line and 1 multihomed Linux machine to handle the T1 line. I'd like to setup a single box to handle both the DSL and the T1 lines.
