We have a full Smoothie box and are suffering from a handful of Mac users getting through with Skype. It seems that no matter what we do (minimum of ports open, skype.com blocked in Guardian), Skype gets through and hogs bandwidth. Is there anything we can do, or is a Skype-specific block coming (similar to the Block Kazaa etc. facility)?

Thank you for this. I have been puzzling over how to get Windows Activation and Updates to work properly through our Smoothwall/Smoothguardian setup and this technique works perfectly.

We have no problems here with XP SP3 running Office 2007 and IE8. What do you mean by 'still doesn't work correctly'?
