webinar.net Network and Firewall Configurations (Ports, Domains, and IP Addresses)

  • Updated

If you or your company uses firewall whitelist to restrict network access to only specific websites or software, then you can use the information below to ensure that your service can connect.

Note. TCP Tunneling can be utilized by a single presenter, allowing the other presenters to use higher UDP ports providing low overhead and higher speeds. If a presenter is having audio and/or video difficulties, they can select the Enable TCP Tunneling checkbox to switch to a TCP connection.

Ports
webinar.net uses WebRTC for the presenters to do presentations.

There are 3 parts in WebRTC:
Signaling
Discovery
Establishing the P2P connection
For signaling, we use secure WebSocket (wss://), which requires 443 port.

Please refer to the following article for more info on the discovery and establishing p2p connection.
