Therefore proving network level connectivity. It isnt a network
related issue its a firewalling issue either locally, remote or in-path.
Was traceroute actually tracert on a windooze machine??
If so, then this proves that ICMP is allowed unfiltered, is UNIX
traceroute allowed? (This uses UDP instead of ICMP)
Next use tcptraceroute IPAddress 80 or tcptraceroute IPAddress 22 to
test where web/SSH traffic fails.
Mail the results.
Enjoy
