Title: 17.1.9 unbound forware reverse lookup
Post by: chris786 on July 13, 2017, 12:43:45 pm

Hello,
i used unbound for a internal DNS. The internal Domain for my Network is .nodomain . All querys for this Domain will be forwarded to an other internal DNS-Server.  So far everything works.

But i need to forward Reverse Lookups for the internal Domain to an other Server. In the GUI isn't such option.

So i put under:
Services: Unbound DNS: General Custom options this:

server:
        local-zone: "168.192.in-addr.arpa."  nodefault
stub-zone:
        name: "168.192.in-addr.arpa."
        stub-addr: 192.168.2.50

Now the reserve lookups work. Later i try it again an i got:

Than i restart the unbound service, and it works for a short time.

Has anyone on Idea what is wrong?  :-\
