I have ZoneAlarmPro 6.x installed on my Win2KPro SP4 workstation (all latest updates installed), which is set up for Internet Connection Sharing. Everything seems to be working fine. However, after a couple of days of use, web browsing becomes very slow on the downstream computerssharing the Internet connection. For example, www.ebay.com will take up to a minute load. However, running a dslreports speed test from the downstream computers shows that the connection speed is OK. Everything remains fine on the ZAPro computer. The only solution is to stop ZAPro, and restart it. The browsing problem is solved by the ZAPro restart, but the issue will pop up a couple of days later.Any ideas as to why the web browsing should slow down on the downstream computers?Thanks!
