Launch ZoneAlarm, select the `Firewall' panel on the left side and then select the `main' opyion in the top. In `Internet Security Zone' put the settings to medium and then click the custom box, in tick the incoming and outgoing `TCP' and `UDP' ports, as you click on each of them you will see another pane open in the bottom, here you can put the port number as 6346. Hope this helps... Haldi
