    Hi Lev.<br>
    <br>
    I am create new virtual host, and run ping from internet.<br>
    <br>
    Ping results 70% packet loss.<br>
    <br>
    But, if i am running ping from virtual host to somebody host in the
    internet and at the same time, i am pinging this virtual host from
    internet.<br>
    <br>
    then ping results 0% packet loss or 10% packet loss. <br>
