gateway for separate networks

[Bob Ababurko]

Hello all-

   I want to install another NIC in my box running 5.2.1 to access another 
network.  Since I have never done this before, I have a question about the 
gateway that the second NIC will use....more specifically, where do I 
configure the gateway for the second NIC.  I have the defaultrouter in the 
rc.conf file for the first, do I do the same or do I add routes to tackle 
this.  If someone could show me any resources on the web that deals with 
this,that would be great.

thanks,
Bob
