Way back when I was setting up the firewall here at the office,
I set up the DNS stuff like this:
o Internal servers for bluetree.ie and 3.168.192.in-addr.arpa
on server1 and server2.
o External server for bluetree.ie on firewall.
o Clients on firewall use internal servers (by specifying server1
and server2 in /etc/resolv.conf).
o Internal servers use firewall server as a forwarder.
I also determined that I needed to make the firewall DNS server
authoritative for 3.168.192.in-addr.arpa, so I made it a slave
for this domain and used access control measures to ensure
that external hosts can't query it.
But... I can't remember why I needed to make the firewall
server authoritative for the internal reverse lookups. It must
have been a fairly obvious reason, because I didn't make a
note of it anywhere :-(
Current theory is that that part of my memory has been
over-written by stuff on COM threading models... Bummer!
Any ideas, anyone?
