What you're asking can be done a number of ways with different levels of complexity, the simplest using routing tables and IPTABLES. Instead of asking this list how to technically do this, I'd suggest that first you describe what you're trying to accomplish at a higher level. And be very specific. Then you will/should receive technical advice better suited to your problem.
I'll do my best to explain in more detail.
The server is running CentOS 5, and it has two NICs on it. NIC 1 is currently active, and plugged into network A - let's say it's 10.1.1.0/255.255.255.224. NIC 2 is currently disabled. I want to enable it, but on a different network - let's say it's 10.1.2.0/255.255.255.0.
Network A is in a fairly well locked down DMZ. I can get to only some devices on network B from network A. Network B has full access to Network A.
Network A and Network B each use different gateways, so I can't use network A's gateway (which is in the DMZ) for NIC 2. NIC 2 would have to use network B's gateway.
I need to activate both NICs because services running on the box need to access devices on network B, and that's only possible from within network B itself.
So, is that enough detail? I'm not sure if I've cleared things up or just made more of a mess.
Thanks for any help.
