Hello Steve,
OH7LZB's AMPRNet VPN is quite simple to configure&fire-up.
It's well documented. Works great almost out-of-the-box.
Myself I use it VERY OFTEN to reach 44-net from my Sony Z1 smartphone.
Also, I installed it on my all Windows&Linux systems to be able
to reach 44-net without need to use own AMPRNet gateway.
Just follow instructions given here:

Best regards.
