Configuring ZoneAlarm Security Settings ( If you're running ZoneAlarm Pro you will probably have considered that most of the "advanced" settings might as well be in Chinese for all the use they are.

If you are not on a LAN (connected to another computer in a network) you can use this guide to give your firewall some real muscle and a new lease of life: Launch ZoneAlarm Pro and click to highlight the "Firewall" tab on the left hand side . In the pane that appears on the right hand side in the section "Internet Zone Security" set the slider control to "High" Then click the "Custom" button in the same section. The next settings page is divided into two sections with tabs Internet Zone and Trusted Zone at the top of the page.
