How to disable the firewall service on Linux

The firewall service in a Linux system is usually provided by UFW (Uncomplicated Firewall) Management, which provides a simple and easy-to-use interface to manage firewall rules. To turn off the UFW firewall service, perform the following steps:

Step 1: Disable the UFW service

sudo ufw disable

This command will disable the UFW firewall service. If prompted for a password, type the sudo password and press Enter.

Step 2: Verify Firewall Status

After disabling the service, verify the firewall status using the following command:

sudo ufw status

The output should show:

Status: inactive

This indicates that the firewall service is disabled.

Step 3: Allow specific ports

If you need to allow access to specific ports, add a rule before disabling the firewall service. For example, to allow port 80 (HTTP traffic):

sudo ufw allow 80/tcp

Step 4: Re-enable the firewall (optional)

If you need to re-enable the firewall, type the following command :

sudo ufw enable

This will re-enable the UFW firewall service and apply any configured rules.
