I am trying to configure two DNS-servers (bind) on 2 linux-servers (server1 and server 2) acting as master for the same domain. server1 is intended as primary server and can resolve a subset of all FQHNs of that domain and is supposed to forward all other queries (including those for 'its own domain') to server2. Apparently this is not possible: If server1 detects a query as being part of the zone that it is configured as master for, it will not forward that query to another DNS, even if server1 cannot resolve that query. This is independent of what forwarding type is configured. Is that correct, or am I missing something?
