I have a Virtual Network Gateway set up using OpenVPN with certificate-based authentication.
I am able to connect to the OpenVPN server on my Ubuntu 22.04 machine, and while connected I am able to reach private IP addresses that are part of the network.
DNS resolution is not working, however.
If I try to ping a certain <dbname>.postgres.database.azure.com, it says "Name or service not known". Whereas if I pinged that hostname in one of the VMs that's part of the same Virtual Network, the private IP gets resolved.
How do I get DNS resolution to work?
