    New host loosing packages - firewall?


    Hi,
    I was just going to change my DNS to the new host,
    but before I started to do some check.
    So I wonder if the host put firewall on pings and tracerrouts,
    and if yes, how can I know if the result is ok in rest of world as the site is international.

    Difference new host and actual host:
    New host:
    Cant ping the nameserver (server or ip) get Timed out.
    If I do a tracerout of nameserver starts ok nothing or aborted using a website.
    The host told my new ip.
    If I use justping.com I get awful result, loss of packages from 70-100%, so imagine is behind some firewall.
    Doing a ping from my pc get better speed than Old host.
    Tried some other websited that only checks a few, and still get some lost of packages, not much but I get.

    Old host:
    Can ping the nameserver without any timed out,
    Can traceroute nameserver ok
    Using justping I get ok on everything
    Pinging using webisted with only a few sites get no lost of packages.

    Thanks in advance

    Ping and traceroute don't use TCP but use ICMP packets and replies may be supressed. Many sites disable ping reply, just try pinging lots of well-known sites and you may or may not get replies. For me www.ibm.co, www.microsoft.com don't reply to ping where www.google.com, www.yahoo.com do.

    My low-end linksys router has a setting to enable or disable ping replies.

    Yep, thats correct, I tried microsoft and could not either,
    but I can ping from my pc the ip, however looks like if I use web tools that ping many sites I get timed out or many lost packages, dont know if new host is bad or that it just block to many pings or tracerts.....
    How can one know?
    Thanks
