Mobile firewall settings
You can configure a network firewall for the XBee Gateway mobile network interface in the firewall configuration page. This firewall reduces cellular traffic and cloaks the device, making it harder to find and reduces the risk of unauthorized access and attacks. While this firewall does not reduce the traffic sent to the device, it prevents the device from replying to it, because the firewall discards the packets sent to it, unless the packets are associated with an established communication (connection).
Note This is available for cellular models only.
See Firewalls and required open ports for more information.
