Enterprise firewall checklist

What to ask IT for when enterprise firewalls break calls

When guests frequently reconnect or can’t see/hear each other on enterprise networks:

• Prefer UDP: Permit outbound UDP for WebRTC to STUN/TURN and peers; avoid DPI that times out UDP flows.

• TURN fallback: Allow relay (TURN) over TCP/TLS when UDP is restricted. Use your own TURN if needed.

• Open ports: Follow the port guidance documented for VDO.Ninja traffic.

• Alternate paths: Try backup.vdo.ninja, WHEP/WHIP viewers, or Meshcast when strict egress control is required.
