I've setup a pdns/pdns-recursor with it's own zones. The pdns/pdns-recursor is behind a firewall with no access to any root-servers.

The pdns/pdns-recursor is working for the local zones and can forward queries to a DNS server through a firewall. But anything outside the environment is queried direct to the root-servers which I cannot reach.

The DNS servers in front of the firewall can query everything outside the environment.

I've tried to use forward-zones pointing to the DNS servers in front of the firewall in recursor.conf and/or an own root-hints file with only DNS servers in front of the firewall to set this up but neither works.


Can you show the recursor config that you tried?

If the DNS servers (caches) in front of the firewall are 192.0.2.1 and 192.0.2.2, then you need something like:

forward-zones-recurse=.=192.0.2.1,192.0.2.2
