In this recipe, we will demonstrate how to add a static route to a network not directly connected to pfSense. Assume that the LAN network uses the subnet 192.168.1.0/24, and there is an external router on the LAN network. The WAN interface of the external router has an IP address of 192.168.1.2, and the external router's LAN network uses the subnet 192.168.2.0/24. The following diagram illustrates our network (the DMZ router is our external Cisco router):
