    Default Blocking Specific Browsers

    Hi All
    I hope I'm posting in the right area. I'm trying to block Internet Explorer from access the Internet. Is there a way to do this in Untangle?

    I guess you could add a firewall rule to block clients with an HTTP: Client User Agent string that matches IE.
    That would block machines that recently used IE or specific version of IE or whatever.
    I suspect this might cause more problems than it solves. I'm sure many windows apps use IE libraries to access the internet, so this will likely break a whole bunch of stuff.

    Beware, thats not truly the same as blocking IE, just machines that recently used IE.
    When a TCP session is created there is no way to see if that specific session was started by IE or firefox or chrome or wget or whatever so there is no way to only block IE. (not at the gateway anyway)

    Personally, I'd block it via GPO. Just kill the iexplore.exe or anything else you want, and it'll error out at anytime they try to launch it.

    Or, do what I did on my network, and change the icon of Chrome to the IE Icon in your image. They still think they're using IE, but they aren't! Win-Win!
