I'm running a Dual Processor G5 with web sharing turned on. However, when I try to access the web site folder through the internet it gives a forbidden error. The check box for web sharing is checked in the service pane, but when I switch over to the Firewall pane, web sharing is grayed out. Does this have anything to do with it?

Does anybody know how to fix this so that I can access the web site folder from the internet? Thanks
