OpenTok Network Connectivity Requirements

This article is now deprecated - you will be redirected to the updated version at shortly.

Running OpenTok requires allowing access to its services over specific ports in order to work. A network administrator in your organization can configure these firewall settings. 

Minimum Requirement: The minimum Requirement is that TCP port 443 is open. Some firewall/proxy rules only allow for SSL traffic over port 443. You will need to make sure that non-web traffic can also pass over this port.

Better Experience: In addition to the minimum requirements being met, we also recommend that UDP port 3478 is open.

Best Experience: For the best possible experience, we recommend that UDP ports 1025 - 65535 be open.

You can test if a network meets the connectivity requirements by using the OpenTok Pre-call test. There is also a Connectivity Doctor app in the Apple App Store as well as the Google Play Store.
