A firewall is a network security system built into an operating system that monitors and manages network traffic according to preset rules. The firewall also aids in the monitoring of networks to determine whether they are trustworthy or not. They also protect your PC from hackers by filtering dangerous network traffic.

The uncomplicated firewall (UFW) in Linux Mint provides a user-friendly interface for managing firewall rules. Its main goal is to make firewall rule management as simple as possible, as the name suggests. Although it is recommended that you keep the firewall turned on, there may be times when you need to disable it, such as when troubleshooting or testing. So this article will provide you the details on how you can disable a firewall on Linux Mint.

There are two main ways to disable a firewall port which are as follows.

  • Using a terminal
  • Using a GUFW utility
