I'm not sure what prompted me to do it, because I don't use this module. But this morning I hit the settings button on my IPSec module and Firefox just sits in a never ending loop of loading settings.
Figuring I had some configuration shenanigans I thought it best to simply try and remove the application. Given the UI was closed to me I went to apt.
apt-get remove untangle-libitem-ipsec
apt-get remove untangle-node-ipsec
The latter won't remove, dpkg -l | grep ipsec lists the node as still installed, yet apt-get remove says it's gone.
However, at this point the app does show in my list of installable apps, and a quick reinstall of my premium package later and it's back in the rack, but we're also back to square one and not able to configure it.
