Hardware: Old Dell Precision 390: CPU: 2 x Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz RAM: 4GB Disk: 150GB 3 Ethernet Ports Installing pfSense:  Install pfSense from iso. Suggested Specs: 32GB disk, 2GB RAM, 1CPU Add network interfaces (2 minimum, I'm using all 3 I have available) Run the installer, no need to set VLAN but do assign interfaces. pfSense up and running! Configuring pfSense: Follow the steps mentioned in this forum post , I've added extra details in bold : Disable Outbound NAT. Go to the 'System -> Advanced -> System Tunables'  and set net.link.bridge.pfil_bridge from 'default' to '1'. Also set net.link.bridge.pfil_member to 0 Bridge WAN and LAN by going to 'Interfaces → Assign → Bridges' Create OPT2 (there should be already an OPT1 since we are using 3 nics)  interface and assign the bridge to it by 'Interfaces → Assignments.  Add an IP address to the bridge interface; this IP is the one you will use to access the firewall lon
