Help with Free Zone Alarm

[mcravenufo]

I decided to use the free Zone Alarm on my main PC.
This PC has Windows internet connection sharing with a dialup connection for my other PC's on the network.
My other PC's now can not access the internet. I added their IP's to the trusted zone but I still don't have acces.

Can some one help me setup free Zone Alarm so that I can have my other computers share the internet on my internet connection sharing PC?
