Comment 1 for bug 1773377

> In order to provide external name resolution for instances designate-bind charm also needs to configure recursion in bind9 config (currently recursion is disabled) and allow queries from IP addresses of compute nodes hosting dnsmasq daemons.

FWIW, Dmitrii opened another bug around recursive name resolution as:
https://bugs.launchpad.net/charm-designate-bind/+bug/1776952

It can be discussed there instead of the scope of designate-neutron relation to pass forwarders.
