What does telnet to port 80 reveal?
If you can get short queries back (E.g. HEAD / HTTP1/0) but not longer
queries it sounds like a PMTUD problem. Does the new customer have Frame
Relay or any other links with MTUs less than 1500?
Windows sets the DF bit on outbound packets, and I believe Microsoft
filter PMTUD ICMP packets.
