🔒 Firewall Requirements for IT Teams
If tests are failing, request these firewall exceptions from your IT department:
| Direction | Protocol | Port | Destination | Notes |
|---|---|---|---|---|
| Outbound | TCP | 443 | Resolving... | TURNS (TLS) - Most firewall-friendly |
| Outbound | TCP | 5349 | Resolving... | TURNS (TLS) - Standard port |
| Outbound | UDP | 3478 | Resolving... | STUN/TURN - Best performance |
| Outbound | TCP | 3478 | Resolving... | TURN TCP fallback |
Important for Corporate Networks:
- ✓ Bypass SSL/TLS inspection for turn.testcribe.com
- ✓ Bypass proxy for turn.testcribe.com (Resolving...)
- ✓ Allow WebRTC/STUN/TURN protocol (not just HTTP/HTTPS)
