I've decided to upgrade the slave to FreeBSD 5.4 using Bind 9.3.2, leaving
for now the master running FreeBSD 5.1 running Bind 9.3.2 taken from an
older version of the ports tree. 

A strawman  FreeBSD 5.4 slave can load and serve all the routeable addresses 
but reports

 Feb  8 20:49:50 ns3 named[275]: transfer of '' from failed while receiving responses: permission denied

This looks like a permissions problem on the slave, but the entire /etc/namedb
subtree is owned by bind with group wheel. On the new 5.4 slave named runs as 
user bind, on the old 5.1 master bind runs as root. 

There is no "allow transfer" directive  on the master, a FreeBSD
5.1 box, so anybody can transfer zones.

One possible trap is that the master and slave refer to each other using
unroutable 192.168.1.xxx IP addresses, is that my error?

There's not much to the zones; www.zefox.com, www.zefox.org and 
www.zefox.net, with ns1.zefox.net and ns2.zefox.net as nameservers.
