Hi all
I have setup a DNS server behind a linux firewall box doing NAT and port
forwarding port 53 to the internal server.
When testing it with nslookup, all the domains/IPs it is responsible for
work fine (forward and reverse), however if I try lookup any other domain
or IP, it fails with (for example)
> 63.219.148.140
Server: ns.mydom.net
Address: 192.168.2.2
*** ns.mydom.net can't find 63.219.148.140: No response from server
regardless of whether i'm testing from the outside or on the internal
server itself (this example was from inside).
So naturally I suspected the firewall and setup an identical config on the
firewall. Lo and behold it works!
Now, another interesting thing is that this "working setup" on the
firewall *does not work* when running nslookup from a pc behind another
(different) linux firewall box doing NAT. Makes me think it's a MASQ
issue since I get this error when either the client or the server is
behing a masquerading firewall, but don't know what.
My named.conf has a forwarders section of course..
Any ideas? I can post more details about the config if you tell me what
you want to see - this is my first foray into a real DNS setup. I'm hoping
this is something simple I'm missing.
