We have had several students find this new filter work around. It's called Ultra Surf from www.wujie.net
It comes from Ultrareach and has been very hard to stop. Has anyone run into this Anonymous proxy?
We have found the the program runs on port 9666.
We blocked all outbound traffic on 9666. Still will not stop it.
Found a forum that says to block server 67.15.183.30. Still will not stop it.
It has to be some sort of bot that has servers all over the place that it changes ports and server IP's.
Anyone, Anyone?

it would be nice if i was possible to block all public web proxy's. extending the http filter with anonymous- web proxy's would be realy great.

Just give up. IT at my school has tried and failed to beat us. You cannot win.

As Bruce mentioned, 7.400 includes the ability to decrypt https at the gateway for inspection. There will certainly be a few issues to consider in implementing this function, but it will provide a substantially improved a level of control.
