Hi. I wanted to know if it’s needed to install a firewall on a linux desktop/laptop. Why yes or why no?

    You are a rock star.

    Okay, I now have new awesome rules! I assigned my other two machines static IPs (192.168.1.3 and 192.168.1.4, respectively). So now I have:

    sudo systemctl enable --now ufw
sudo ufw default deny
sudo ufw allow from 192.168.1.3
sudo ufw allow from 192.168.1.4
sudo ufw limit ssh
sudo ufw enable

    SSH still works, everything is awesome. Thanks again 👏👏👏
