SBS 2003 DHCP Server using Linksys Route

Hi,
I am installing SBS 2003 on my server that has 2 NIC cards 10/100 and 1000. II am using a Linksys router with the DHCP server disabled. I am trying to determine the correct IP addresses and dns server to use with the cards. When I go through setup SBS 2003 wants to assign 192.168.16.2 to the local network. How do I configure the Gigabit NIC to use the Linksys router for Internet when the default IP fpr the router is 192.168.1.1.
