# How to install the superlight mirage-firewall for Qubes OS by using saltstack
|
|
# Tested on Qubes v4.1 and mirage v0.8.5
|
|
# After the install, you have to switch your AppVMs to use the mirage firewall vm created by this script e.g. by using "Qubes Global Settings"
|
|
# inspired by: https://github.com/one7two99/my-qubes/tree/master/mirage-firewall
|
|
|
|
# default template + dispvm template are used. Possible optimization is to use min-dvms
