Pfsense WAN with Cellular LTE/4G

Using pfsense for WAN Redundancy with Cellular LTE/4G

I work from home a lot and I need reliable internet connectivity to workplace. As a result, I decided to implement a failover WAN connection into my firewall. I use pfSense as my firewall which combines power and flexibility with ease of configuration.

The Hardware: NetGear LB2120 LTE Modem

While researching options, I decided on the Netgear LB2120 4G LTE modem since it has Gigabit port(s) and can be used with external antennae.
