Thanks both – so if I do
sudo ufw allow from 192.168.0.99 to any port 22 then am I doing anything other than saying 192.168.0.99 can ssh in to this machine? This is what I’m trying to achieve but the “any” is confusing me somewhat – though the rule itself does seem to be doing what I want.

If I’m opening port x from ip address y on my network with the following command sudo ufw allow from y to any port x …then where does the “any” come from? Anyone know? Seems strange to say “any port” then list the port number – unless I’ve misunderstood the rule.
