Opening two ports at once in ssh

Using ssh server to enable remote access, new to Ubuntu as of last week.

I need ports 22 and 222 open, but can only get 22 open after installing the ssh server. I know thats the default port.

Anyone know how to open both ports? I'm pretty sure I have done all I can on the router side of things. I'm running Ubuntu 16.04.

The ssh daemon from openssh-server can take multiple Port directive (in /etc/ssh/sshd_config) for assigning multiple ports to the single ssh daemon.

You need to indicate the port numbers after each Port directive in /etc/ssh/sshd_config file e.g.:

Port 22
Port 222

Now restart the ssh daemon, for Ubuntu 16.04:

sudo systemctl restart ssh.service
