Sounds like you're talking about how to get your (local dhcp server) dhcp server to
pass the DNS server entries you get from your ISP (local dhcp client) ??? True?

There's a line like:
option domain-name-servers AAA.BBB.CCC.DDD;

Where you can supply the list of DNS servers that dhcp clients will
hopefully set their resolv information too after getting an address
dynamically from your ISP's dhcp server.

So you run a dhcp client on eth0 (to your WAN to get info from your
ISP)... and you run a dhcp server on eth1 (for example) to feed
your local hosts with IPs and DNS address information.

Are you running dhcpd?... where do your clients get their IPs from?

I may not have fully understood your issue.  Am I on the right path
to what you're looking for?
