Have you tried zerotier? Another option is to get a vps with unlimited bandwith and setup ovpn server on it. Then you need a router that can connect as a client to vpn. This way you will have a public ip and you dont need to mess with tunnel services. A vps with public ip is about 10 bucks a month.
I have been to some shady pubs and nightclubs in my life, non of them had so much violent people as a linux bugreport thread.
