Maybe you could explain? Traceroute works fine here....

These are all local:

Now, with the last one, I attempted to traceroute to something
non-local, outside. The Net Nazis closed all the ports
except mail, ftp, domain, and web so I can't send anything
outside to a non-standard port (like traceroute does) so
it fails with the "* * *"
