"Traceroute packets" is extremely vague. As a general rule, if you want to discover a complete path between endpoints that are expected to communicate using 80/tcp, trace the route using 80/tcp. (Not that it's ever expected to see protocol-specific drops in a core or across a transit or peering edge.) Joe
