Description

Creates firewall qube, an App qube "sys-firewall" and a Disposable qube "disp-sys-firewall". By default, "disp-sys-firewall" will be the "updatevm", the "clockvm" and the "default_netvm".

If you want an easy to configure firewall with ad blocking, checkout sys-pihole instead.

Installation

Before installation, rename your current sys-firewall to another name such as sys-firewall-old, the old qube will be used to install packages required for the minimal template. After successful installation and testing the new net qube capabilities, you can remove the old one. If you want the default net qube back, just set sys-firewall template to the full template you are using, such as Debian or Fedora. Before starting, turn on sys-firewall-old or yours default_netvm and check if DNS is working, after that, proceed with the installation.

• Top:

qubesctl top.enable sys-firewall
qubesctl --targets=tpl-sys-firewall state.apply
qubesctl top.disable sys-firewall
qubesctl state.apply sys-firewall.prefs-disp

• State:

qubesctl state.apply sys-firewall.create
qubesctl --skip-dom0 --targets=tpl-sys-firewall state.apply sys-firewall.install
qubesctl state.apply sys-firewall.prefs-disp

Alternatively, if you prefer to have an app qube as the firewall:

qubesctl state.apply sys-firewall.prefs

Usage

You should use this qube for handling updates and firewall downstream/client qubes, in other words, enforce network policy to qubes that have sys-firewall as its netvm. Read upstream firewall documentation.
