Means to privately connect to my home server other than Tailscale?

Wireguard is blocked in my country, so I no longer can use Tailscale or other Wireguard-based solutions. My home server is behind a NAT. What other ways of secure private connection can I use?

Port forward your SSH-server. You can forward ports through SSH to access web services or others running on the server or anything else in the network.

But only allow access through keys. And maybe try to use a different port than 22. That usually gets hammered a lot, trying to find accounts with weak passwords.
