This document provides instructions for configuring a pfSense firewall to use multiple WAN connections for failover. It describes setting up a Clear Wireless 4G connection as the primary WAN and using the existing office connection as a backup. Specific steps include adding the WAN interfaces, creating a gateway group for failover, and configuring firewall rules to use the gateway group. Initial testing showed the Clear Wireless connection providing adequate speeds for typical office use while offloading over 6GB of data from the office connection in just 3 days.
