Setting Firewall and Proxy Configurations to Prevent Video Blocking
The NextGen Healthcare Web Real-Time Communication (WebRTC) service provider requires access to specific User Datagram Protocol (UDP) ports for the best video and audio experience. You must open the Transmission Control Protocol (TCP) port 443 by changing your firewall settings. To ensure optimal video and audio quality, you must also do one of the following.
- Open UDP ports 10000–65535 to all inbound and outbound traffic. These ports permit WebRTC to establish direct connections to media servers and minimize lag and latency by bypassing relays.
- Open UDP port 3478 if it is not feasible to open all UDP ports on your network. This approach allows media data to flow through Traversal Using Relays around NAT (TURN) UDP. This is a step above TCP. However, an additional server is required to relay packets. This approach can introduce latency and/or connectivity issues.
To allow video visits for your practice, you may need to adjust the settings on both the network and Group Policy Object (GPO)/computer levels. In the web access protection settings (the name of this setting may vary by product), you must set the following addresses as allowed:
To permit communication with WebRTC servers, you must allow the following IP addresses:
- 34.203.254.0/24 (34.203.254.0 - 34.203.254.255)
- 54.172.60.0/23 (54.172.60.0 - 54.172.61.255)
- 34.203.250.0/23 (34.203.250.0 - 34.203.251.255)
- 3.235.111.128/25 (3.235.111.128 - 3.235.111.255)
- 34.216.110.128/27 (34.216.110.128 - 34.216.110.159)
- 54.244.51.0/24 (54.244.51.0 - 54.244.51.255)
- 44.234.69.0/25 (44.234.69.0 - 44.234.69.127)
