Hi Richard,

Have you verified that you have set the flow source interface for the 
UDP Netflow packets. You should set this in your Cisco`s configuration 
along with the usual ip flow export destination and ip flow export 
version configurations. I believe the syntax is: ip flow export source 
<interfacename>

But don`t quote me on it. This is totally by memory. :-)

Cheers,

Francois
