To drive home this point I have been testing Neth on a Rasphberry Pi 4 and it has done everything I normally virtualize Neth for (OpenVPN, Account Manager, Guacamole and Email/SOGo). I have been super impressed with what this cheap PoE capable board can do.
The only thing I can’t currently do on this unit is to get Guacamole to properly send out WoL packets that I know Nethserver can do via terminal.
