Hi,
Firstly, Openvpn is setup and works perfectly, so thanks guys, however the problem i have is that on the client PC there is an application ( of which i have no control) which is hard coded to effectively perform a DNS resolve using specifically the generic google DNS server address. so it would be like typing like nslookup <theirdomain> 8.8.8.8

However OpenVPN is blocking this request presumably due to the "Block IPv4 DNS Requests from other apps" which appreas in the log files.

Is there a way in the clients .ovpn file to "Allow IPv4 DNS Requests from other apps" so that DNS Request to 8.8.8.8 ( or 8.8.4.4) still operates,

This is using OpenVPN Connect 3.3.1 (2222) WIndows
Many Thanks
Chris

What setting causes openvpn client to log on connection: "block IPv4 DNS requests from other apps"?
