## Firewall settings

### Client

**XReach** makes use of the ephemeral port range on the client side (49152-65535) to establish a TCP/UDP connection to the server. TCP is only going to be used when UDP is not available or is restricted in ways that make it not suitable for media streaming. (Not all browsers support the media connection over TCP, however.) The necessary firewall inbound and outbound rules for **XReach** mobile are added automatically during installation.

The client needs to be able to communicate with the following remote ports:

* 8443 TCP

* 5379 TCP (TLS)
* 49152-65535 UDP (recommended, but not mandatory)
