Disable firewall linux

Ubuntu comes with ufw (uncomplicated firewall) installed by default. This is a frontend for iptables/nftables, the built-in Linux firewall, and is meant to make firewall management a bit easier.

Stop/Disable Firewall in Ubuntu

If you find the Ubuntu firewall interfering with connections on your system, one option is to disable the firewall completely.

Warning: it’s recommended that you add custom firewall rules to allow certain ports and access through the firewall, rather than disabling the firewall completely.

1. To turn off the Ubuntu firewall, use the following command in terminal.

$ sudo ufw disable Firewall stopped and disabled on system startup

As seen from the output, the command will also disable the firewall from starting automatically upon system reboots.

2. To delete all configured ufw rules and set the firewall back to default settings, execute the command.

$ sudo ufw reset Resetting all rules to installed defaults.

Proceed with operation (y|n)? y

3. You can also use commands to bypass the ufw interface and interact directly with the system firewa
