How to log in to SSH by add. port?

Question

linux

Hello.
The goal is this:
there is a standard port 22 for SSH connections, it works and only 1 IP can connect to it.
How to make 1 more port for SSH connections so that you can freely connect to it, while 22 would also work with filtering by that type, and the second port would work without filtering.
It is desirable for more details)) Thank you!

Answer 1

just add one more port to /etc/ssh/sshd_config Before
:
Now:

Port 22
Port 2222

And the IP restriction is most likely configured through iptables, that is, there will be no default restrictions for the new port.
