A few real world examples of using tcptraceroute to trace through
firewalls that traceroute(8) has trouble with.  These are all sites
that pass TCP SYN packets on to hosts sitting on the clean side of the
firewall, and which don't filter ICMP time exceeded messages leaving
their network.  All examples listed below were captured on July 1st.
