A unikernel firewall for Qubes OS. This site will help collecting information about the mirage firewall, an interesting project from “talex5”.

To learn more about the Mirage Firewall, please make sure to read

The Mirage Firewall for Qubes OS is a low ressource firewall, which uses a much smaller footprint compared to the default (“fat”) sys-firewall.

This page is only to write down how to build the mirage firewall for Qubes OS. Please make sure to read the above links to understand more about it.

Most information from here has been put together reading the original docs above and following the discussion in the Qubes OS User Mailinglist / Google Groups: https://groups.google.com/forum/#!topic/qubes-users/xfnVdd1Plvk
