By default, UFW is set to deny all incoming and allow all outgoing traffic. This is a good starting point
for most users.
To change this, you can use the following commands:
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow 22
sudo ufw allow ssh
sudo ufw allow 6000:6007/tcp
sudo ufw allow 22/tcp
sudo ufw allow 22/udp
sudo ufw delete 1
sudo ufw delete allow 22
sudo ufw logging on
sudo ufw logging off
sudo ufw deny in on eth0
sudo ufw deny from 1.234.31.117
sudo ufw allow 22/tcp from 203.0.113.102 on eth0
