Now use these recommended rules:

sudo ufw limit 22/tcp
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw enable

If you are using the application LocalSend, also run this:
```
sudo ufw allow 53317
```

This will allow localsend to work properly with the ufw rules above.
