I have setup UFW with:
sudo ufw default allow outgoing
sudo ufw default deny incoming
sudo ufw allow ssh
sudo ufw allow from 123.456.78.9
sudo ufw status
:
To Action From
-- ------ ----
22 ALLOW Anywhere
Anywhere ALLOW 123.456.78.9
22 (v6) ALLOW Anywhere (v6)
How ever I am still able to connect to the node from other IPs on ports other than 22. What am I doing wrong? Tried reloading and restarting.
This is a very basic installation, at this point I have really only created a new user.

The issue was that I was using Docker which does not respect the rules of UFW.

Hi
Are you certain you’re attempting to connect from an IP other than 123.456.78.9 (your home/office IP)? Because that IP is clear to connect to any port on your server.
Cheers

The “ufw allow ssh” is allowing SSH from any location. Dropping that and being more specific will help to accomplish your goal. I recommend reviewing this, it’s pretty tame as far as documentation goes, and full of examples:
