For some reason, our DNS resolution does not work correctly over SSTP VPN or S2S connection in azure.
Everything works fine directly in the Azure environment. Additionally, I get the correct DNS servers when establishing SSTP connection but the resolution does not work, DNS requests just time out.
So what has been tested so far:
- configured P2S connection manually and forced the tunnel
- appended connection specific suffixes
Any ideas, what I should look into?
