No local DNS when connected to SSL VPN

From my Android phone using openvpn and the ovpn config from my Sophos box, I can connect to my network.

I can get to my servers from using their IP, but I cannot get hostnames to resolve.

In System > Administration I have DNS turned on for VPN

10.0.0.1 is my sophos box and also how my LAN uses for gateway.

Sophos is my DHCP server.

I have a DNS server on 10.0.0.4 that is a raspberry pi running pi-hole.  It is configured to pass local name resolution to the sophos box.

My VPN Settings:




Any idea what I am doing wrong?

  • this allows access to the DNS-service of the firewall.
    If you use the firewall-IP for DNS, this may work.

    If you wish to use an different DNS-server, you need a firewall-rule (not a local ACL) to allow this access.

    Create a LOG-and-DROP rule at the end of your firewall rule set and check for dropped packets.
