Firewall is the first thing that comes to mind.  Second would be some 
sort of PathMTU discovery black-hole.

One way to check for that would be to run a TCP_RR test and see if that 
"works."  If it gets a non-zero result, it suggests an issue with large 
segments (the netperf default request and response size being one 
byte...).  If it gets a zero result, it suggests something else like 
perhaps firewall.
