Master-Slave with IPv6 only?

Hello,

I have this situation:

both the master and the slave are dualstack (have both an IPv4 and IPv6 
address),
but the master is not reachable on IPv4 (RFC1918 IPv4 without a port 
forwarding);

how can I prevent the following on slave side's log:

Nov  7 10:23:01 nilsholgerson named[20881]: client 17.17.17.17#27763: 
view auth: received notify for zone '...'
Nov  7 10:23:01 nilsholgerson named[20881]: zone .../IN/auth: refused 
notify from non-master: 17.17.17.17#27763

named.conf on master has this:

   notify-source 0.0.0.0;
   transfer-source 0.0.0.0;

the same in named.conf on slave;

Thanks,
Walter
