You need to allow rule in firewall port 53 tcp n UDP. There is no other way...
Thanks

Hi Samir, it's not a firewall issue. The correct firewall rules are in place however they only allow access to a restricted list of external DNS servers. The question I have posted is around whether I have implemented the correct solution on the BIGIP DNS to provide external DNS resolution.
