  • Block access to BBC iPlayer and MSN Live Messenger

    Folk

    I'm using ISA 2006 and I need to block access to the BBC iPlayer, that is to say I need to prevent staff viewing videos with it.

    Additionally I need to stop chat through MSN Live messenger and MSN Messenger. I've tried the advice given in KB925120 which to be fair does look pretty straight forward but I can still connect to the services from my PC.

    It has to be me where the problem lies with applying the instructions in the knowledge base article so I'm hopeing that someone can give me the benifit of their experience here.

    Any advice on blocking iPlayer, MSN Messenger and Live Messenger would be gratefully received.

    Regards
    Philip

      Thanks for that, it is the guide I have perviously followed but I have gone through it again anyway and unfortunatelly Windows Live Messenger still allows me to sign in

      It's almost as if MSN Live Messenger is somehow bypassing the proxy server but I don't see where those settings for doing this might be.

      It shouldn't be this tough to achieve a simple thing but I am pulling my hair out at the moment!

      Hope that someone can help some more

        AFAIK MSN Sign-In is encrypted - no network device is going to pick that up, if that's the case. Having signed in, can you send any messages?

          Well The authentication isn't the important factor.
          With ISA you can simply block the Signatures which can be sniffed.

          I just manage to block the latest version of Windows Live Messenger without any problems.
          How are your clients configured? SecureNAT? WebProxy? Firewall Client?
          I've done a quick test with all 3 of them and no issues at all.

          What I've done is at my outgoing HTTP rule I've clicked with my right mouse button and have choosen for Configure HTTP
          After that I went to the tab Signatures
          There you can give it a name and a description and then you do the following:

          Search in: Request headers
          HTTP Header: User-Agent:
          Signature: Windows Live Messenger

          Edit:
          I assume that the BBC iPlayer is an application or is it a website?

            BBC iPlayer is a website offering two means of watching BBC TV programs. The first method uses a peer-to-peer technology with the iPlayer Download Manager to download files. It uses a similar method to BitTorrent - i.e. all the time you're downloading, you're also uploading.

            The second means is via Video Streaming.

              Well in that case for the Download Manager it should be possible to do something like the same as what I've just showed with Windows Live Messenger.
              For the other rule it would be an option to allow the website specifically but deny video.
              I can't test it though because of this

              Currently BBC iPlayer TV programmes are available to play in the UK only

              Ok I tested it with:
              http://www.veronicatv.nl/web/show/id=96520/langid=43 (dutch TV)

              What I've done is above the regular allow internet access rule I've created 1 rule
              A deny rule for HTTP for the a URL set for that website where I only set the content type to video.
