Unable to Resolve Azure Private DNS Name with WARP Client in Cloudflare Tunnel Setup
What is the issue you’re encountering
I am facing an issue with DNS resolution for a private SQL Server endpoint in Azure, while using a Cloudflare Tunnel and Zero Trust setup
What steps have you taken to resolve the issue?
Troubleshooting Steps Taken:
Verified the private DNS zone is properly linked to the virtual network in Azure.
Confirmed that the WARP client configuration includes access to the private network.
Ensured the Cloudflare Zero Trust policies allow traffic to the private network endpoint.
Checked DNS settings on my laptop to confirm that the WARP client is directing DNS queries through the tunnel.
Tested resolving the DNS name directly from the tunnel VM, which works fine.
Request for Assistance:
I would like to resolve the issue where the private DNS name of the SQL Server endpoint cannot be resolved from my laptop. Specifically:
Are there additional DNS configurations needed in Cloudflare Zero Trust or the WARP client?
Should any custom DNS resolvers be configured in the WARP client settings?
Are there diagnostic tools or logs I can check to pinpoint the issue?
What are the steps to reproduce the issue?
Setup Details:
Infrastructure Overview:
A virtual machine (VM) in Azure has been configured as the Cloudflare Tunnel endpoint.
The Cloudflare Tunnel is set up with Zero Trust policies.
The WARP client is installed and configured on my laptop to communicate with the tunnel and resources in the Azure Private VNET.
Private Network Configuration:
A private network endpoint has been created for SQL Server in Azure.
The VM hosting the Cloudflare Tunnel can successfully resolve the private DNS name of the SQL Server endpoint.
Problem Description:
From my laptop, where the WARP client is configured, I am unable to resolve the private DNS name of the SQL Server.
Other resources paired to the Azure Private VNET can be accessed without issues through the WARP client.
