Hm, sorry, I didn't know that option was available only in the Pro edition. Now that the subject has been brought up, has anyone managed to use ICS with other software firewalls? That's precisely why I gave up on Sygate.

Under the "Firewall" option in the program window, click the "Advanced" button. A smaller window named "Advanced Settings" will come up. Under the "Internet Connection Sharing" section, choose the option "This computer is an ICS/NAT gateway". That's all. You can leave your Trusted Zone setting on "Medium". Never tried it on "High", though.
