Rule schedule from ical feed?

  • My searches so far have come up empty, but I'm interested in using an ical feed of events to activate / deactivate a firewall rule. Say activate 10 minutes prior to the event start and deactivate 10 minutes afterwards. These events don't occur on a recurring basis that can be expressed by the current pfsense rule scheduler, they occur at specific non-regular dates and times. Has anyone done something like this with pfsense or would anyone have any interest in working on a solution with me?
