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.
