icastGo is a cloud-based web and video application. Normally all ports are accessible, but some corporate firewalls or proxies might need need to whitelist some ports.
| 80, 443 (TCP) | Outgoing Ports for HTTP and HTTPS |
| 40000-49999 (UDP) | Outgoing WebRTC ports for sending browser audio/video |
We strongly recommend that the *.icastgo.com domains (and subdomains) be whitelisted in any relevant proxy servers. In particular, the application uses both long running HTTP requests (Sever Sent Events) and WebSockets that aggressive proxy filtering or caching could interfere with.
icastGo is supported in all browsers for participants attending the webcast.
