[cobalt-users] Qube 2: Howto forward DNS requests?

[Joerg Kalisch <cobalt@xxxxxxxxx>]

Hello

I want my Qube 2 to act as a local DNS server for my private network
at home. My ISP gave me a multidrop mailbox for a subdomain (i.e.
mysub.domain.com).

I have done the following settings on the DNS parameter page:

qube.mysub.domain.com   -->                      192.168.0.5
client.mysub.domain.com -->                      192.168.0.2
192.168.0.5             -->                      qube.mysub.domain.com
192.168.0.2             -->                      client.mysub.domain.com
mysub.domain.com        --> ...high priority --> qube.mysub.domain.com

This works very fine for my. The DNS is resolving correctly and mails
can be send / received.

Now i want to forward any DNS request (which can not be resolved by
my local configuration) to another DNS server. This should be tranpa-
rent for my client.

I know, that i can enter a secondary forward domain server, but i
have to specify the domain. Can i use a wildcard or a negation like

!mysub.domain.com --> 128.128.128.128

here? (Which means: Forward any request to a subdomain which is not
mysub.domain.com to the DNS server with IP 128.128.128.128).

The remote DNS should only be contacted if the IP can't be resolved
by the local configuration. Does anybody have a solution how to mana-
ge this problem?
