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.

Any idea what I am doing wrong?

  • Just a crazy idea, but have you tried another VPN client? I've used OpenVPN client for years now, and a while back (v20?) I could no longer get DNS. I wasn't using it for a while, but got back to it recently (v21 beta, maybe v20) and tried using the Tunnelblick client (on a Mac) and suddently DNS works. Same ovpn file, same everything on the firewall, but now it works. I wonder if the OpenVPN client has a bug -- at least in terms of using an older ovpn file.
