Have you considered using a port forwarding service such as Ngrok or Serveo? Ngrok is a paid service, but there are free accounts with limitations. Serveo kills inactive connections, but I've written a python script which keeps the connection alive.

Have a look at my github if you're interested: https://github.com/DedSp4ce/DedTunnel

I also made a post in the hacking tools section if you'd like further explanation.
