I'm using the Connection Sharing from XP and ZoneAlarm (free). At first, ZA blocked my second computer. Then I added the 2nd PC to the trusted zone, and now ZA blocks the 2nd PC's requests for internet. How do I make the network work???
The only way to setup ICS, XP and ZoneAlarm (ZA) is to download and then purchase ZoneAlarm Pro 3.x
It has a wizard that will configure XP ICS and ZA to work together. I had similiar issues with my home network and the pro version corrected the issue. I do not know of or think that there is a way to otherwise bypass it w/o pro version 3.x.
