What Are Rainbow Network Requirements?

Basically the traffic between your LAN and Rainbow server only requires outgoing flows towards :

• TLS 443 to Rainbow Server and possibly for iOS notifications (APNS),
• UDP 3478 to Rainbow Turn Servers for audio/video calls
• TCP/5228-5229-5230 for Android notifications (FCM) for Rainbow Room and pure WiFi smartphone.

Note : In case domain white-listing is implemented on the LAN, all traffic towards Rainbow server is at destination of Rainbow domains *.openrainbow.com
