Internal Master with external slaves

[Kevin Darcy]

We've had similar issues with our "hidden master" setup, and someone 
here suggested it was because our machines are multi-homed, and 
sometimes the NOTIFY packets come from an address which is unknown to a 
given slave, and thus are rejected. If this is the root cause, it should 
be fixable with some combination of notify-source and/or allow-notify, 
but I haven't got around to it yet...
