What is the alternative to ssh -R 80:localhost:80 [email protected] for port forwarding?

Question

linux

There is a virtual machine with the address 192.168.1.111 on the server with the "white" address 123.123.123.123.
It is necessary that the sites from the virtual machine be accessible from the outside through the external IP of the main server.
Forwarding an http port through ssh works, but is there a _faster_ and easier alternative?
For example through iptables?

Answer 1

Install nginx. In the standard configs there is an example of setting up reverse proxying. Plus, there is configuration flexibility and caching.
