Domain and Port Whitelisting

Zuddl uses WebRTC technology for its real-time engagement functions and requires network configuration for environments with restricted access. If you are behind a firewall or a VPN and are trying to attend an event, you may encounter errors or connection failures.

In order to prevent such failures, Zuddl recommends whitelisting certain domains and ports, thereby providing a faster and efficient service and an overall better meeting experience. The below illustration depicts how you can allowlist Zuddl and WebRTC ports and domains to grant access to your resources through a firewall or across a VPN.

Note: If the above whitelisting cannot be implemented because your organization is behind a stricter firewall with many restrictions, please reach out to your customer success manager.

Note on websockets:
Websockets need to be allowed on the device browsers (like Google Chrome, Microsoft Edge, etc.) and also in the network whitelist.
