Firewall for Ubuntu 14.04 LTS

For whatever reason, Ubuntu 14.04 does not seem to come with a firewall.

There are however two packages which provide, both a firewall and a handy GUI front-end for it.  UncomplicatedFireWall is the main package (ufw) and the GUI is gufw.

To install:

apt-get install gufw

This will install the front-end and the dependent packages

To turn it on:

ufw enable

The default is to block all incoming traffic.

To update and add your own firewall rules and allow incoming connections


The GUI is quite intuitive and allows advanced users the ability to create their own custom rules.
