A bit off-topic, but do you know if Skype works through that proxy? Skype falls back to attempting connections over port 443 if it can't get others to work, and as it is primarily a UDP-based product - like openvpn - I've always wondered if their "port 443" traffic was true SSL or just some other encrypted "skype protocol". i.e. if an organization has a policied BlueCoat transparent HTTPS proxy, and general egress filtering, does Skype work? -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
