The ports aren't blocked as another site (example.eu) hosted on the
1.1.1.1 server works fine. The working site has both nameservers
pointed to that same server (on two different IP addresses on eth0 and
etho0:0). Only the example.de site which has one nameserver on the
1.1.1.1 machine and the second nameserver on 1.1.2.2 is giving me a
headache.


Hello Dothan.
You said: "The working site has both nameservers pointed to that same
server (on two different IP addresses on eth0 and etho0:0)."
So the question is "Are you sure you answer to queries on the proper
interface?"
Maybe you (for instance) receive a query on eth0:0 (1.1.2.2 ?) but
answer on eth0 (1.1.1.1 ?)...
What is your default gateway? 

Ciao.
Stefano.
