Better off using a Mikrotik router board with an LTE card then do pptp to 
some internet safe IP space.

This is what I do to connect my GB3EI Node in the Outer Hebrides. works well.

I can give you a config if required.

Problem with 3/4G dongle is they do Internal NAT and you cant do the port 
forwarding.
