firewall
Firewall LTE modem physically separates the LAN / WLAN to WAN and acts as a safety check of all data flow
between networks.
The firewall also protects against denial of service attacks (DoS). The purpose of this LTE modem is to allow

misuse of sensitive data and system logs, which may represent an important part of your network
infrastructure.
LTE modem is the interface between LAN / WLAN and Internet. Because it can serve as a secure gateway
for all data traffic between the Internet and LAN.
