Hi,

I have noticed that iperf, among other UDP-based applications (such as 
nc/nc6), fail when server host has multiple addresses. When the server has 
multiple addresses, receives using its address A, but sends back a 
response using address B. Now, if A happened to be the default address of 
the host, address B usually then equals to A and it actually works. 
Otherwise it just fails.

Is this the case also with you? (Probably it is different issue, though)
