I want to be able to mirror the UDP port 53 going to my unbound instance for the purposes of testing out a new external DNS firewall service which we want eventually to start forwarding to. I want to be able to e.g. compare the responses with and without the service.
I don't see any unbound feature or module to do this. Forwarding seems to go to one of the external caching servers given in the forward-addr: section. Any ideas of tools which allow me to do this? I am running unbound under both Ubuntu 20.04 LTS as well as OpenBSD 6.9 Thanks in advance. --- Russell P.
