I need people to reach my servers over SSH and RDP. Both ports are blocked outbound at many companies, especially the large ones. However, I also suspect that in 90% of companies there is nothing to stop tunneling SSH and RDP outbound over port 443. Ignoring the security concerns of that, I am wondering:
1) How many of you can tunnel RDP over 443 at the companies you've worked at [let's not discuss current companies for username protection]?
2) If you can't tunnel RDP, then do you know what's blocking it. Is it the firewall or some other specialized security box at the perimeter?

Many companies block the CONNECT method, and the IP connections (without dns name). That's especially useful for blocking Skype.
