Lookup on Local Domain Name Returns Nothing

Two things:

1 - you do not have any RR for "mynet.mine.nu" in the zone file, so Bind 
returns the information you have given it. See below for proposal.

2 - You have made your own server authorative for "mynet.mine.nu", so it 
has no reason to forward this query to the dyndns server, which you 
expect it to do. You have told your own Bind that it has all existing 
information about this zone by setting this zone "master". If you ask 
from the outside you get ths:

silver:~>dig mynet.mine.nu

; <<>> DiG 8.3 <<>> mynet.mine.nu

What exactly do you want to achieve? You must have an inside look and an 
outside look and answer for yourself what address should I get for each 
of these hosts on the network. Once you have this list the picture may 
be clearer to you.
