[K12OSN] How to convert a server from two NICs to one NIC

What's the best way of converting a two-NIC server to a single NIC? Or
more precisely, moving the DHCP service from eth0 to eth1?
I've got a two-NIC server that is having trouble using the DNS info
coming from a Linksys WRT54G which is connected to the internet. Here's
a crude diagram:
My plan is to switch them around so the server is connected to the
internet (there's a firewall in between there) and use the Linksys as
just a WAP by not plugging anything into its upstream port. Not being
certain I can make this work, I may have to leave the Linksys as the
primary internet gateway, and just turn off its DHCP service, and let
the ltsp server provide DHCP. In this case, I don't want the ltsp
server to act as a gateway; rather, I'll need it to be/act like a
single-nic server and still point to the Linksys as the default gateway.
The server's already running and providing file and print services, so
I don't want to rebuild it. If I have to go this route, I think it's
just a matter of having the ltsp server's DHCP service running on eth1
instead of eth0 where it is now. Can I make that happen by just
changing all the addresses using in /etc/dhcpd.conf?
