    I was wondering if someone could shed some light on this little curiosity.

    US ping (sourced from different networks, including cable customer in
    NE) to the consumer grade residental israel dsl cpe (currently cisco
    871) look really nice and sweet, gotomypc works alright, consumer is
    enjoying overall internet experience.

    vnc from customer to US is a non-starter. ssh from US almost never
    works. ipsec performance is horrid.

    traceroute/tcptraceroute show packet loss and MUCH higher rtt than the
    corresponding direct pings on the reported hop entries.

    Is this some sort of massaging or plain just "faking it"? Or is such
    things merely net-urban myth?

    Here is a traceroute snippet
