What are the alternatives to OpenVPN?

Question

VPN

How can you organize access to remote systems? Now works through OpenVPN. But the problem is that it is necessary to update all packages, including the Operating System itself. Because everything is so outdated. If you update, you will lose access, encryption keys, and so on. I would like to have some alternative. For example, like TiamViewer, which organizes a remote network without any problems. But remote computers are used without an interface. Console only.

In general, you need to organize a VPN to remote computers that work through a WIFI router. And you need to periodically access them from the main server. Perhaps there are some good ready-made services

Tell me how to do this?

Answer 1

The keys will not be lost if you save them and put them in the new system.
