You need a router to connect 2 networks.

You have to create a static route.

Whichever one is on eth0 should be your "default route" (the one you list as "GATEWAY=" in /etc/sysconfig/network.) This would typically be the IP to the router/switch.

You then setup a route for your secondary card (e.g. eth1) in /etc/sysconfig/network-scripts in a route-<device> file (e.g. route-eth1).
In that file you would need:
GATEWAY0=x.x.x.x
NETMASK0=x.x.x.x
ADDRESS0=x.x.x.x

Where GATEWAY0 is the IP of the switch/router that the second network's IP goes to and NETMASK is appropriate to your /24 network. ADDRESS0 is the IP range you want.
