Remove the line below as you are unnecessarily delegating
10.1.168.192.in-addr.arpa to yourself and occulting the
PTR record (that you want to be there) in the process.
> 10.1.168.192.in-addr.arpa. IN NS oak.mydomain.com.
The following two records have the wrong owner names once
the origin is appended, e.g. 10.1.168.192.1.168.192.in-addr.arpa.
> 1.1.168.192 IN PTR firewall.mydomain.com.
> 10.1.168.192 IN PTR oak.mydomain.com.
They should be:
1 IN PTR firewall.mydomain.com.
10 IN PTR oak.mydomain.com.
