A Raspberry Pi Sized x86-64 SBC / OPNsense Example using a Single NIC!

Wish you could have a single board computer (SBC) with the same form factor as the Raspberry Pi but was x86-64 instead of ARM? Radxa has created the first x86-64 SBC (that I am aware of) that mimics the form factor of the Raspberry Pi 4 with their X4 model. I thought it would be fun to demonstrate using OPNsense with a single NIC since I have not yet created any guides using a single network interface.
