How to proxy port 22 to another machine?

Question

linux

Good afternoon!
Is it possible to somehow proxy port 22 from one machine to another?
Now DNS resolves the ip address of the machine with Nginx (it, in turn, proxies to another machine where the private git is located). You need to make a port 22 proxy for Git.
