Posted on 2007-07-30

I have a 501pix firewall, I am not using proxies. I am trying to block all streaming radio, when i look up port numbers I seem to get a listings of hundreds of port number that do not deal with what i am looking for. I am looking to block a port or a range of ports. Does any one have a place for me to look or suggestions.

    mm,  I do not believe with a PIx501 you will functionally be able to completely eliminate any Internet radio,  you need an application gateway.   I know that Sirius internet radio, uses a bunch of ports, depending on what's open and available.....

    Have your HR department put an internet radio/bandwidth clause in the handbook....

    roger,  No proxy needed,  There a burden.  Try a baracuda Web filter,  inexpensive for what it does, and SOOOO Easy to put on to the network....  Users have no clue it's there, and it can hook up to your AD you can review all the activity, Bar graphs on top 10's much much more....  Infact, will practically keep your entire systems virus free.

    Not selling them, I just had a client purchase it a few day's ago, and was hoping it would take a little longer than it did....   $$$....   But for baracuda's sake, they definately have the setup down....

    Now is this a hardware device, if that is the case we are looking for ways to do this without buying any additional equipment. In fact I am trying if it comes down to it I can block the website via acls, but I was trying to block all forms of it, not just as the user discover which ones they can listen too.

    i understand.  Well to tap into all the traffic, which is what you will need to do, there has to be 1 of 2 things.  A HUB between the router and main switch, get a program called Winshark, and watch what is being used....  Then block the needed IP's, web addresses, or ports ont he PIx.
    OR If you have a managed switch, and can "forward" all ports to you...

    Use winshark to capture, then import the log into excel, and start manipulating...
    It will take some time, but you'll really get that puppy tuned well...
