Outside world blocked
It all started on a night when we had a lightning storm. The power went out once for a second, the computers turned off. Turned back on, everything was fine. Than this happened again a couple minutes later. Turned everything back on... what's this? The outside world can't see the computer when the external ip is trying to be accessed. I didn't change anything, and now I'm trying to figure out what happened and how to fix it. Any suggestions?
