Port Availability & Whitelisting

Port Availability & Whitelisting

The Flex device is configured to be a DHCP client by default.

Please note that the Flex device uses a Web Secure Socket connection in order to communicate with the Device Portal.
To run smoothly within a LAN the following ports need to be available for communication with the Device's services:

  • Port 80 -> HTTP (HTTP traffic)
  • Port 443 -> HTTPS (HTTPS traffic)
  • Port 123 -> NTP (NTP time traffic)
  • Port 53 -> DNS (DNS lookup - needed by your browser and units to lookup domain names)
If stream playback issues persist, it is recommended that you whitelist *.overheadmusic.com

NOTE: If an asterisk does not function as a wildcard to allow "(anything).overheadmusic.com" then whitelist all of the following URLs:
  1. streaming.overheadmusic.com
  2. streaming1.overheadmusic.com
  3. streaming2.overheadmusic.com
  4. streaming3.overheadmusic.com
  5. streaming4.overheadmusic.com
  6. streaming5.overheadmusic.com

Other Solutions would be enabling the QoS on the router to accommodate and prioritize traffic. See your network manager for this feature.
