Ubuntu Touch, is the Ubuntu phone operating system. The operating system is already on Bq phones, not to mention the Nexus 4 devices that can "wear it." But did you know that the new operating system comes with a complete firewall by default?
A firewall installed by default is not something you can usually find in mobile operating systems. Definitely you can install firewalls in other operating systems, but they are not the same thing.
Some Ubuntu users may remember a firewall called UFW, which means Uncomplicated Firewall, or in Greek, "Easy Firewall."
As it turns out, UFW is installed by default on the operating system Ubuntu Touch, but must be enabled by the end user.
Of course if you are not experienced user, you'd better not mess with the UFW. She is one application aimed at experienced users as firewall policies will need to be configured. Of course if you want to try it, activation is easy. Connect via ADB and run the following command:
sudo ufw enable
"Ubuntu's default firewall is UFW. Developed to facilitate the configuration of the iptables firewall. UFW is user friendly and provides ways to create a host-based firewall in IPv4 or IPv6. By default, UFW is disabled, ”says the official wiki of the application.
There are too many commands to play, as long as you know what you are doing.
