      I have OpenVPN (PureVPN) configured and it works well… generally.  However, lately, they have been having some issues with DNS.  So, while the main connection works fine, I wanted to "augment" the DNS that is sent over by OpenVPN with additional Google DNS servers.  In those cases, when OpenVPN DNS fails to respond.

      I remember when originally setting up OpenVPN in 2.3.3, I could not get the DnsLeak test to pass as it kept going to other DNS services outside my OpenVPN setup.  Finally, I got it to work by telling DNS Resolver that the outgoing network should be via ONLY PureVPN.  So, now, I want to go back to where 8.8.8.8, 8.8.4.4 in addition to the OpenVPN DNS are consulted during the lookup.

      No matter what I do in the 2.3.4, I cannot get it to work.  I am posting pictures of what I think to be relevant setups/configurations and I have a suspicion it has something to do with my firewall rule.  But I am not sure how to resolve.

      General setup, with 8.8.8.8 and 8.8.4.4 configured
      DNS Resolver Configuration
      DHCP configuration for LAN
      Firewall rules for LAN

      What am I missing?  In addition to the DNS provided by PureVPN, I want to also send queries to 8.8.8.8 and 8.8.4.4, but all the queries are going ONLY to the PureVPN DNS.
