Microsoft Update + ZoneAlarm = No Internet Access

With the last Microsoft patch this past Tuesday, if you were a user of ZoneAlarm, you were no longer able to access the Internet. I happen to be one of those users. I could get to my router, but not the Internet. Other devices on my network, of course, also were able to access the Internet. When I finally discovered that ZoneAlarm was the problem, I found a reference on the ZoneAlarm site. Apparently the patch was fixing quite a serious flaw in Internet addressing.

I find it funny that fixing the flaw caused ZoneAlarm problems. Anyway, if you're finding this post, then you were not affected or you have solved the problem.
