eth card setting for dhcp server

When setting up a dhcp server for a private network 192.168.foo what
should the setting on the server ethernet card be. Do I set both the IP
and the gateway to 192.168.0.1. The server has two cards one connected to
the net the other to a hub. The dhcp server is also the firewall, so
internet traffic will flow through it. I am not sure what the setting on
the private network card should be. Thanks for any input.

Yes...

Your firewall uses it's own gateway. This gateway has nothing to do with
either the LAN behind your firewall, or your dhcpd settings.

When giving out gateway information, your dhcp server should tell clients
that their gateway is the firewall's internal IP address, 192.168.0.1.

Your firewall is the gateway for the clients on your LAN.

From my firewall:

[root@crazy root]# route -n
