PTR records are not resolving. When using the following command:
set service dns forwarding authoritative-domain 0.2.168.192.in-addr.arpa records ptr 36 target mydomain.local
I then commit, save and running:
nslookup 192.168.2.36
Produces a NXDOMAIN error.
Try this instead:
set service dns forwarding authoritative-domain 2.168.192.in-addr.arpa records ptr 36 target mydomain.local
That is the zone is “2.168.192.in-addr.arpa” who then contains “PTR 36 mydomain.local” and is resolved by “nslookup 192.168.2.36” or “dig 36.2.168.192.in-addr.arpa”.
