Configure pfSense bridge over multiple NICs as LAN

In the past I’ve used “raw” pf on FreeBSD as a firewall for a variety of situations both large and small, but this week I started playing with an inexpensive, fanless, multi-NIC box as a potential firewall and router running pfSense. Interestingly, the first thing I realized is that I could not find in pfSense any completely user-friendly (read: single checkbox) option to turn all but the WAN-designated NIC into a single bridged “LAN”. Seems like a pretty basic thing someone would want to do as a home router, or simply avoid the switching overhead of packets amongst different subnets. A quick search for other solutions didn’t turn up one that I thought was really complete, hence this guide.
