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.
