[netperf-talk] Static IP adress stalls netperf ?

[andrew.west at mindspeed.com]

seems the problem is default gateway setting.
If I comment this out, can still launch netperf  .  (I'm just running the 
local loopback test to check)
However my test setup (PC at 10.1.1.2 on WAN side of a router)  DOES have 
a default gateway of 10.1.1.1, so I need it there.

A few questions, the answers to which may help shed some light:

*) What was the IP and mask you got via DHCP?

*) What was the exact netperf command line?

*) Does netstat -an still show a LISTEN endpoint for the netserver?
