That seems a bit pricey considering you still need a few items. I’ve had a QOTOM for quite a while that has served me well. Looks like they have Intel four 2.5 Gb ports with an N100 for pretty cheap.
Throw a stick of RAM and an m.2 drive in there and it would be cheaper and more capable than the Banana Pi. You could even throw Proxmox on there and virtualize pfsense.
