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?

  • Rule 16 looks good.
    .. but no hits ... :-(

    You may use a DNS-test-Tool at your Phone, or connect a windows-device and use nslookup.

    Check firewall log again, if you see traffic from VPN-network and Port 53.

    Which Browser do you use ... possible the browser use its own DNS

    Sophos firewall is the gateway for all devices in your network (pihole to?)
