One way is to take away the users right to change proxy settings, this
does assume you have win2k/XP on the clients and some form of domain
management (NT policy or AD)
Then remove the connections tab from the users and set the policy to not
use a proxy.
You can do this by hand if you have no policy functions or by using the
ieak to create a new install.

Subject: Proxy Port detection
In our enterprise we have URL filtering capabilities
and we restrict the usual sites (Porn, Sports,
We do not use a proxy, so everyone goes directly to
I believe that some users put in their proxy settings
an anonymous proxy using port 80 (which is obviously
allowed) and in that manner avoid the restriction of
the URL filtering.
- Blocking all the anonymous proxy is imposible and
would be a full time job
- The use of a proxy is not an option right now
Is there any way to detect this type of traffic
I'm sure someone had this problem before...
Any help would be appreciated.
