If you or your company uses a firewall allowlist to restrict network access to only specific websites or software, then you can use the information below to ensure that your service can connect.
WebRTC
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 this article for more info on the discovery and establishing p2p connection.
Domains & IP Addresses
For most firewall or proxy systems, webinar.net recommends specifying a allowlist of DNS names for webinar.net services so that outbound connections can be made. The list of webinar.net domains currently includes (but is not limited to) the lists below.
Presenter Servers
Presenter Console requires the following ports open for the Presenter Servers.
Protocol | Firewall Ports | Description |

TCP Tunneling Server
Presenter Console requires the following port for accessing these TCP Tunneling Servers. This is only required if TCP Tunneling is enabled. TCP Tunneling is only required when UDP ports 16384-32768 are not allowed by the firewall.
You can read more about TCP Tunneling here.
