I am using NAT on a debian sarge gnu linux box to share a cable
internet connection. The linux box has two ethernet cards. One (eth0)
is connected to the cable connection and gets it's connection details
from my ISP's DHCP server. The other (eth1) is connected to a network
switch into which I have connected a very simple wireless access
point. My clients are mostly windows machines with wireless cards.

I have got DHCP to work and it is leasing IP addresses over the
wireless connection to the clients which is great. However I want the
clients to automatically get the correct DNS addresses and I am not
sure what to do or even where to start.

Is DHCP-DNS what I want?

Should I be running my own DNS server (which caches the others?) or
simply get the clients to use the DNS servers automatically provided
by my cable company?

Should I just give up and hard code the DNS servers into the clients
on the assumption that my cable company will keep them on the same IP
for a long time?

Please be verbose and patronising ;->
