    Hi velu and welcome to the forum,

    a quick search for "Ultrasurf" and i found this thread.
    http://forums.untangle.com/web-filte...ultrasurf.html

    So try using OpenDNS or blocking the TCP port mention in the other thread.

    I think the only method to block ultrasurf ( or any other local proxy non instalable that use port 443) is with the option "Categorize HTTPS traffic by IP address" in Esoft, and trust in Esoft list.
    The port 443 is unblockeable.
    The soft ultrasurf is a small exe , can be run from a pen drive, not need to install.
    This class software is the nightmare for censorship in countrys like China or Iran.

    Confirmed
    WIth esoft I can block ultrasurf to view "know and popular" porn sites like playboy or hulster.
    It would be interesting to try unfamiliar sites, if you know of any let me know.

    Another marketing argument to sell Esoft!! Ultrasurf is really difficult to block with the most UTM according to what I read in forums.
