DNS discovery / FreeBSD Firewall

[Mark Moellering]

Hello,

	I have a FreeBSD 6.1 firewall (pf) between my cable-modem and router, with an 
IP address set by DHCP.  My ISP recently changed their DNS server IP adresses 
which I have set manually on the computers on my home office network.  
	The questions is; How do I have the internal network machines get the DNS 
server settings from the Firewall?  The two scenarios I can think of are: 
that the Firewall also acts as a DHCP server and somehow set the DNS of the 
internal net machines to the Firewalls resolv.conf entries; or I can have the 
Firewall act as a DNS server/relay and forward the DNS requests.  
	Is one of these preferable or easier than the other?  Are there other ways to 
do this?  I feel there must be someone on this list who is doing the same 
thing and has a solution or can at least point me in the right direction.  
Any and all help is greatly appreciated.

Thanks in advance,

sincerely
