>From what I can see from your messages your problem is that you are behind a
firewall.

Best practice when setting up a firewall is to disable ICMP, ICMP is the
protocol that ping and tracrt runs over, if this has been done you will get
no response. 



I hope this helps

.tracert google...


Yes you need to put in the gateway. The gateway is there to handle any calls
off the subnet

do a tracert to a machine local to the subnet ie off the same hub/switch and
give us those results. this will confirm if your machine tcp stack is
screwed or not.

Pings are not proxied.  Proxying is a way of caching information so that it
can be re-retrieved more quickly (and cheaply).

What you mean instead of a "proxy" is a firewall.  A firewall is in place to
protect a local network from inbound packets, by restricting the type of
data that comes through, and through which methods it is allowed to come
through.  The firewall can also be configured to stop certain types of
packets from going out from the local network to the internet, for example
pings and traceroutes.

For example, at my work, the firewall (which is a router) is configured to
allow packets to be transferred outward only by a single server on the
network.  It is also configured to block a large amount of data that's
coming into our network.  The server that's allowed out is doubling as a
proxy server, so it is caching HTTP and FTP requests so that if the same
file is requested twice from the Internet, it's looked up locally instead.

In my case, pings go out via this server, through our firewall/router, and
out to the net.  It would seem that in your case, your firewall is blocking
ping requests.

Try doing a traceroute and seeing how far you get -- that way you'll know at
which point your pings are being blocked.

For example:

tracert google.com
