I have all but given up getting DNS to work right on a server that is
running two IP address, one on an internal DNS zone and one on an external
DNS zone. I know there are issues with doing this if you do not have both
DNS zones configured properly but I am pretty certain that the internal DNS
server is configured correctly since none of my clients are having any
issues at all. The only computer on the network that is having any issues
is the server that is sitting on both zones. The server is running NAT and
Firewall services and is also providing OD authentication services to the
internal zone.
The computer is set up with the internal hostname of fileserver.occu-med.com
which is located at 10.0.0.1. The secondary interface (en1) is set up on
the inside of the network, and the primary interface (en0) is set up on the
outside of the network.
If I run "host 10.0.0.1" in the terminal, I get "1.0.0.10.in-addr.arpa
domain name pointer fileserver.occu-med.com." which is correct.
If I run "host fileserver.occu-med.com" in the terminal, I get
"fileserver.occu-med.com has address 10.0.0.1" which is also correct.
Am I correct in assuming that forward and reverse DNS are set up correctly?
If so, when I run "-sudo changeip -checkhostname" it returns:
Primary Address = 209.234.xxx.x (External IP)
Current Hostname = fileserver.occu-med.com
DNS Hostname = mail.occu-med.net
Technically, the Primary Address is correct (Have to have external interface
set up as Primary in order for NAT to work properly) however I have no idea
where the computer is pulling mail.occu-med.net as assigned to the external
interface. The domain mail.occu-med.net is definitely NOT assigned to
209.234.xxx.x (that domain is hosted externally, and is assigned to our
ISP's mail servers) and there is no internal occu-med.net domain.
I did have this server set up as the DNS server when I was first messing
around with it, so is it possible that the old DNS records are fudging
things up? I recently switched all DNS services from this server to a
Leopard server in the hopes that it would correct the issue. Unfortunately
this didn't work.
Does anybody have any pointers as to what the problem could be?
Thanks,
James
