I'm torn between the Raspberry Pi and the Banana Pi R2. I want something just for running a VPN and firewall for multiple computers simultaneously. Wifi and 1 ethernet at the bare minimum, but the more ethernet the better.
I checked your ideal hardware table thoroughly and after filtering everything I came up with the Banana Pi R1, which is no longer in production. The R2 has better specs but according to your recommended HW table Wifi and HDMI are unsupported.
I'm also considering the Raspberry Pi. According to your same table the Raspberry Pi 2 B 1.2 is the latest fully supported board, so I was thinking I would get that one. Unfortunately, it has no Wifi. Can I just plug in a Wifi USB dongle?
I would also be fine with the Raspberry Pi Zero W, which according to your website is also fully supported, but has no ethernet. Not sure how I'm supposed to use OpenWRT on the Zero if it has zero ethernet ports.
So, I'm trying to decide between those three. Advice? Thanks!
