Hi, I live in Germany and only have public IPv6. My address changes only very, very rarely and has never changed in the time I’ve been self-hosting.
I also have a very small, pretty cheap VPS with static IPv4/IPv6 – which would seem like a great fit for some sort of tunneling/proxy setup. Now comes the question: What/how should I use it? I would like to not have the additional latency for IPv6 enabled hosts, can I just setup a reverse proxy for IPv4? Would Tailscale work for my usecase, what are some resources you found useful when using it?
Currently, I’m just hosting everything IPv6-only and hoping my address never changes, but that does not work for everyone, as especially many new buildings with fiber optic connections still only have IPv4 (strangely).
Fair comment, I should qualified my answer: I use an ssh tunnel with auto-reconnect option, wrapped inside a systemd service. In all this years, I still have to run into a problem that wasn’t external (server down, no internet at home etc) I agree that wireguard is the proper solution however it requires a lot of extra configuration and support in both ends, which now is prevalent but not so much 5+ years ago. Also for a single port solution, ssh is so much simpler, practical and reliable, you only need an ssh user at the other end.
ExecStart=/usr/bin/ssh -NT -o ServerAliveInterval=60 -o ServerAliveCountMax=3 -o ExitOnForwardFailure=yes -R localhost:YOUR_PORT:localhost:YOUR_PORT SOME_USER@YOUR_SERVER
