[Pdns-users] Pdns not sending NOTIFY's from local-address

I'm configuring powerdns for non-native master operation on a
multi-homed machine. It's talking to a non-native powerdns slave
somewhere else. MySQL replication for master-slave operation is not an
option (as the machines and thus database belong to different
companies), and I just want to have the machines be each-others 'backup'
The machine I'm running as master has a dedicated extra IP address for
all DNS stuff (so we move the IP and all DNS stuff to another server if
we ever need to). It seems like powerdns is properly listening at just
the dedicated DNS IP (according to netstat) but it's NOTIFY's are being
sent over the machines default ip according to the routing tables,
instead of the DNS IP, and because of this the slave is rejecting the
NOTIFY's (because they're not being sent by a known master).
Is there a hidden master-address config setting or something? It would
be perfect if powerdns would use that if present, or otherwise default
to the first listed local-address.
The only other workaround that doesn't require me switching IP's would
be to start mangling/SNAT'ing packets using iptables, and I *really*
want to avoid that if possible...
Thanks for your help on this one, and regards, Gili.
