Overview

Protectli offers 4G LTE Modems and service subscription plans. An overview can be found on the main 4G LTE page. One of the options is an internal modem, the MDG100. In order to use the MDG100, an Operating System (OS) must be installed on the Vault and configured to recognize and utilize the 4G LTE Modem. This article describes how to configure OPNsense  to utilize the MDG100 Internal 4G LTE Modem.

Accessories

The Internal 4G LTE Modem, MDG100, includes micro coax cables and antennas. When the MDG100 is ordered with one of the Vaults, the MDG100 is installed and tested by Protectli at the factory. If the modem has not been installed, install the modem in the proper slot, connect the coax cables and attach the external antennas.
