Also, when you send a ping, what is the response? If it's a "destination
net not found," then check your routing tables along the path to the target.
If it's a "destination host not found," then your target isn't alive for
some reason. If it's "request timed out," then check your routing tables on
the path *back* to the originator of the ping - the "real" response doesn't
know how to get back to you, so all it can do is time out.

A suggestion is to a 'trace' and see the results. It would show who is
dropping the packet.
Could you send a 'trace' result to the list?
