	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.
