I'd like to setup my RPi 3B+ as a mobile network (USB LTE or 4G or 3G modem) router and VPN server.
I have couple of network devices in a location where only mobile internet access is possible. I need to connect to these devices from outside.
I've found tutorials how to setup mobile router and VPN server, but it is always separate installatoni.
Is it possible to do it on one RPi? Any ideas?
