Re: Strange Network Problem (TTL?)

Sorry I was a little short on information. We can ping other hosts on the
remote network without problems. For example www.galileo.com is on the
same class C as vpn.galileo.com ... we can reach www.galileo.com
consistently from all of our computers (Linux and Win98/NT/2000). This is
why I think the problem is with the remote host and not our (or even their)
network.
How could a ping from Linux and Win2k work but not from Win98/NT? How can
pings returned to a Linux and win2k box on the same network show such
widely different TTLs?
Here is a traceroute from behind our firewall to vpn.galileo.com, hop 15
and 21+ are not reponding. A traceroute to the functional www.galileo.com
is exactly the same:
