Ah, but not necessarily so.
I installed an embedded Linux firewall/modem for my father, the 
Actiontec DualPC modem. The Linux firewall/modem knew the DNS servers 
for the ISP and was providing DHCP for my father's PC, but I was still 
having problems getting to some sites. Once I added the ISP DNS server's 
IP addresses to the PC, then the problem was gone. Now I'll grant you 
that the PC is running WinXP, not Linux, but it was still a simple 
matter of making sure the box inside the firewall knows which DNS 
servers it should "query".

And then again, I could be totally off base. But hey, it's worth a shot. :-)
