I leave you beta scripts for installing all. I installed by hand every package in this way and my UT 6.1 is working with all!
This not use UT gui for all products if someone wants to get inside the same panel feel free to upgrade this cause I don't know how to modify untangle panel.
I make my own panel in php for this "addons"
Use it at your own risk, i recommend to run command by command some lines requires you to supervise them and edit files
I can't paste the scripts cause I have not a lot of posts here so I put the script in a file:
