Remote ssh connection to local network?

Question

SSH

Hello everyone, there are 10 computers on the network. It is necessary for everyone to connect via ssh through an external address. At the same time, it can reach up to 600 customers per machine at a time.
How can this be implemented?

Answer 1

For each computer, assign its own port (instead of 22 \ tcp), and forward this port on the router. The number of clients is not important, as long as there is enough channel thickness and router performance (for example, some SOHO router can start to bend even from hundreds of clients).
