Can anyone give me a quick walkthrough on how to set up an access rule to block a TCP port? I need to stop people from playing a game (World of Warcraft) and I need to block 3724. I've tried various combinations of inside outgoping, inside incoming and I just can't seem to get it. I would really appreciate some help with configuring this through the ASDM GUI.
Jeetu thanks for the information. That is very useful. However the port 3724 is the one that is used for hosting the game. Rest of the ports are just used for downloading the patches by the Blizzard Support. I think just blocking 3724 should be enough. However as per documentation on Blizzard Support Site they have mentioned the following ports to be opened in order to run this. 3724, 6112, 6113, 6114 and 4000. http://us.blizzard.com/support/article.xml?locale=en_US&articleId=21077
I think we can start by blocking 3724 and of it does not help we can move on to blocking other ports as well. Moreover Jason please send the running config or the screenshot of the ACL you are configuring using the ASDM,
