Use UFW on Debian and Ubuntu: install, open ports (allow/deny), check status and avoid accidentally blocking SSH on port 22.

Install UFW

With UFW (Uncomplicated Firewall) you can manage ports on Linux easily.

sudo apt install ufw

Open and close ports

Open port (example 8080):

ufw allow 8080

Close port:

ufw deny 8080
  • ufw status: Shows firewall status
  • ufw enable: Enables the firewall
  • ufw disable: Disables the firewall
  • Important: Do not block port 22 (SSH) or you will lose access!
