Do you mean MS Proxy Server?

This does not handle telnet AFAIK, as Telnet clients are not proxy aware (the way that web clients and FTP clients are).

Traditionally the way you'd proxy telnet is to have a program running on the proxy server to which you telnet, and then you tell it where you really wanted to connect to.

Telnet clients are not proxy aware, but if you punch a hole through the proxy server, port 23, then it doesn't really matter - clients should be able to access external telnet servers, as long as something else along the way isn't blocking things.

Do you mean I have to telnet through the port 23?
Basically, if Proxy Server is not the one blocking, then..
The whole situation is, before we have the proxy server, every client computer under the domain controller has a static IP, an external static IP that outside can directly connected to.
Now, all the client computer only has a local IP.
I don't know if that provides more information for the question.

For some reason, I didn't install the MS Proxy Client on my machine.  And after the installation, telnet works.
So, anyway, points go to the first one who mention that Proxy Server has nothing to do with telnet port.  It's just the client machine settings.
