    Hi All,

             We are using TMG 2010 and created a rule to deny Chat in the environment, but it is not working. I am willing to block entire Instant Messaging option using TMG including chat embedded in gmail. Please provide a solution if this can block or not...

    Thanks in Advance....

    Hi,

    you can use the URL protection Feature of TMG to block this URL category. Another was is to use the HTTP Filter of TMG to create a HTTP signature to block the Messenger

    Hello,

    I would agree with others.

    You can block chat based on categories filtering: http://blogs.technet.com/b/isablog/archive/2010/01/03/categories-for-url-filtering.aspx

    Another option is to block chat based on signatures. More here: http://technet.microsoft.com/en-us/library/cc302627.aspx

    Hi,

           I have seen the link earlier 

    http://www.microsoftnow.com/2010/06/blocking-skype-and-other-im-protocols-in-forefront-tmg.html

    and this is not helping me. I have configured the policy exactly as specified in this link but could not achieve it.

    Hi,

    Thank you for the post.

    Please make sure that the default gateway of the client machines point to TMG internal ip address.

    Hi,

    Thank you for the update.

    If you have set another gateway, the traffic will bypass the TMG server. So you are unable to block Chat using TMG server.

    HI Pras,

    Could you please show your chatting denied rule you have on your TMG Server?

    What exactly are you trying to block? If it is Skype, then you must have HTTPS inspection enabled to be able to block it.

    Make sure you also have the 'use non primary categories' box ticked on each filtering rule.

    What do the log entries on TMG say when someone accesses a chat site?
