  • If supported by your external proxy or firewall, you can now open your network by DNS instead of IP range. Application Proxy services require connections to *.msappproxy.net and *.servicebus.windows.net only.

Earlier versions

If you're using an Application Proxy connector version earlier than 1.5.36.0, update to the latest version to ensure you have the latest fully supported features.
