    I believe it's been said here many times before, but when in public venues,
    the only way to be sure about anything in regards to traffic filtering and
    manipulation is to VPN into your corporate network and bypass all that.
    Unfortuanately, it makes streaming the latest episode of Heroes a little
    jerky.

    Just recently in NYC, the hotel "internet" connection did intercept
    any UDP traffic to *:53, redirecting it to their resolver. Which did
    not only serve their own A records for names that should have returned
    NXDOMAIN, but also returned "better" answers than you normally would
    get (requesting pages from www.weather.com delivered pages from
    www.accuweather.com
    ). Of course it even did that after I had paid and clicked through
    their walled garden site.
