Networking setup

When setting up your ViewSonic entity, confirm that your network meets the requirements listed in this document. Each ViewSonic service has its own set of requirements designed to ensure stable performance. Use this guide to prepare and validate your network environment.

Entity Management

Entity owners and admins should whitelist the following domains to ensure all users in the entity can run ViewSonic software without issue.

Ports

Configure your firewall to allow access to ports used by various ViewSonic services.

Mandatory:

• TCP port 443 (HTTPS): Outbound is required for general operation and activation.

Wireless screen sharing requirement (optional):

• UDP and TCP port 3478: Bidirectional to the WebRTC servers.
• UDP ports 50,000 – 65,535 (RTP / sRTP / RTCP): Bidirectional to the WebRTC servers.

These ports are optional. If blocked, media will be proxied using TURN on port 3478. The WebRTC protocol is only used for screen sharing. Verify that these ports are open on your network firewall if you wish to use screen sharing.
