How to add multiple port listen SSH on FreeBSD

The way to do is:

1) Edit sshd config “/etc/ssh/sshd_config”

vi /etc/ssh/sshd_config

2) Uncomment the line “# Port 22” and add new lines according to how many listener ports you wants to be available for the SSH service on your machine.

In this example we wants to add a new listener for port 10022 and still uses the default ssh port 22, so the line should be like:

Port 22
Port 10022

3) Save the config file and restart the SSHD

/etc/rc.d/sshd restart

– Also sometimes is important to allow just some users, so for that feature you need to uncomment or add the line

Multiple users should be listed on the same line

AllowUsers admin1@ admin2

And reload that changes after save the config file executing:

/etc/rc.d/sshd reload

Source: FreeBSD ssh

Multiple users should be listed on the same line, like so:

AllowUsers root@ admin
