I've had little snitch installed and running without issues for 2-3 years now. I reinstalled OSX from a time machine backup 2 weeks ago, and after booting up reimported a backup of the little snitch rule set. All has been well until 2 days ago when all web browsing started being blocked.
Little Snitch Little Snitch is a firewall application that monitors and controls outbound internet traffic.

The current situation is that when I turn off the network filter I can browse the web, but as soon as I turn the filter back on, all web browsing is blocked. I tried restoring the rule set again from the known good backup, but it's still blocking.
There haven't been any changes to the networking or OS that I am aware of.
