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.
are there OTHER networks on the WAN accessed via B's gateway/router ? network A's gateway is the internet route?
if B's gateway has routes to the rest of 10.x.x.x, I'd just define a static route like 10.0.0.0/8 -> B's gateway/router's IP, and leave the DEFAULT gateway as network A's internet/DMZ router.
