Just built a new computer, and had to reload ZoneAlarm from scratch. (I'm using ZoneAlarm Pro) But now I'm getting an odd issue.
The main computer works by using Internet Connection Sharing (ICS) for three other computers and a wireless access point. Internet Zone Security is on High, Trusted Zone Security is on Medium. I've set the option 'This computer is an ICS/NAT gateway' with the correct local address. This is how it's alway been. And when I first start ZoneAlarm, everything works fine.
However, after about 1-3 hours ZoneAlarm will suddenly cut off all internet activity to the ICS computers. The main computer can still browse the internet, but the other three computers get disconnected permantnelty. The only two things I can seem to do (both of which are incovient) to bring back the connections are:
(1) If I shutdown ZoneAlarm and restart it, everything will work again... for another 1-3 hours.
(2) If I got to the Firewall settings and change the Internet Zone Security to Medium, then everything will work until I switch it back to High.
I've already uninstalled and reinstalled ZoneAlarm a few times, using the cleaning method everytime, but this issue always comes back. Does anyone else have a clue to what is going on?
Operating System:Windows 2000 Pro
