[Pdns-users] cisco css and Received an answer (non-query) packet

Hello all,

I just moved our DNS system to run behind a cisco css 11154 load balancer...

I configured 2 machines running pdns, they are using private ip addresses. 
On the css I configured a dozen content rules, that all say the same 
thing... load balance dns traffic for the dozen public ips across the two 
dns servers...

very frequently, pdns logs the error: Received an answer (non-query) packet 
from one of my public ips

Any body using css load balancer for dns traffic, with private IPs to share 
their tips with me?

Thanks a lot.
