   sudo ufw status numbered   
   sudo ufw default deny incoming   
   sudo ufw default allow outgoing   
   sudo ufw allow 22   
   sudo ufw enable   
   sudo ufw status numbered   
   sudo reboot   
      
   netstat -tulpn   
   tcp        0      0 0.0.0.0:22   
      
   When I run from my home   
   sudo nmap -p 22 -sUV SERVER_IP   
   22/udp    open|filtered ssh   
      
   But, when I run   
   sudo nmap -p 22,80,12345,55555 -sUV SERVER_IP   
   22/udp    open|filtered ssh   
   80/udp    open|filtered http   
   12345/udp    open|filtered unknown   
   55555/udp    open|filtered unknown   
      
   I don't have these ports open.   
      
   Why every udp port is open?
