Firewall Exceptions

 

    The ESChat client requires specific network routes to communicate between the host device, such as a smartphone or computer running the client, and the remote servers.  

If your device has a firewall enabled or is on a network that operates behind a firewall, such as many corporate wired and Wifi networks, it may be blocking connectivity to our server and/or audio from passing through.  If you experience problems or need assistance on changing the settings of your firewall ,  please contact your IT staff.

This document is specific to AWS cloud deployments:

NOTES:

  • ALL  PORTS ARE OUTBOUND ONLY

  • WE DO NOT CONTROL IP RANGES REQUIRED BY THIRD PARTY PROVIDERS
