Getting Started

The basic firewall configuration begins with connecting the pfSense® appliance to the Internet. The pfSense appliance should be unplugged at this time.

Connect one end of an Ethernet cable to the WAN port (shown in the Input and Output Ports section) of the pfSense appliance. The other end of the same cable should be inserted into a port of the Cable or DSL modem. The modem provided by the ISP should have multiple LAN ports. Any port should work.

Next, connect one end of a second Ethernet cable to the LAN port (shown in the Input and Output Ports section) of the pfSense appliance. Connect the other end to the computer.

Warning

The default IP Address on the LAN subnet on the pfSense firewall is 192.168.1.1/24. The same subnet cannot be used on both WAN and LAN, so if the default IP address on the ISP-supplied modem is also 192.168.1.1/24, disconnect the WAN interface until the LAN interface on the firewall has been renumbered to a different subnet (like 192.168.2.1/24).
