Expanded UDP Connectivity Validation with the TURN Health Check
The existing UDP connectivity check in Azure Network Connection (ANC) validates STUN (Session Traversal Utilities for NAT) reachability. We’re enhancing this check to also validate TURN (Traversal Using Relays around NAT) connectivity, giving administrators a more complete view of relay-path readiness. With TURN health surfaced alongside STUN on the ANC page, administrators can more quickly spot and remediate relay-path issues before they impact users.
