Hi Frank
sorry I'm quite new to dnsdist :-)
I thought that a rule like this could work
> newServer({address='XX.YY.ZZ.ZZ:53', pool='remote'})
> addAction({"IP1", "IP2"}, PoolAction('remote'))
IP1 and IP2 are the IP addresses of the two authorative nameservers for
the zone in my tests. XX.YY.ZZ.ZZ is the IP of recursor B
I thought the rule above would send any dns paket that go to IP1 or IP2
via the other recursor.
But if I tcpdump on recursor B I cannot see the request pakets from
recursor A coming in.
Any idea what I'm missing?
Thanks a lot
