Without the firewall enabled, clients can access internet fine.
With the firewall enabled with just a single rule (allowing access to a couple of named websites), the clients no longer can reach those websites, webpages indicate that DNS is not resolving.
Do you need to setup a DNS rule and if so how (tried it does not seem to work).
