If your company uses a firewall allowlist for restricted network access, please refer to the following details to ensure seamless connectivity for your service.
WebRTC
Webinar.net uses WebRTC for the presenters to do presentations.
There are three parts in WebRTC:
Signaling
Discovery
Establishing the P2P connection
For signaling, we use secure WebSocket (wss://), which requires 443 port.
Please take a look at this article for more info on discovering and establishing a P2P connection.
Domains & IP Addresses
For most firewall or proxy systems, webinar.net recommends specifying an allowed list of DNS names for webinar.net services to make outbound connections. The list of webinar.net domains currently includes (but is not limited to) the lists below.
Presenter Servers
