Bi-directional traffic cloning possible?

This is not true, at least not intentionally. Clone pool functionality is bi-directional. It does clone both ingress and egress packets (at least that is how it is implemented). If this is not working for you, please contact support.

 

 

You can also configure the clone pool to be on the clientside and/or the serverside. This distinction is important for cases where the BigIP is modifying the content, such as when terminating SSL. Cloning on the clientside would copy the encrypted traffic whereas cloning on the serverside would copy the unencrypted traffic.

 

 

To answer the second part of your question, though you could certainly setup a rule to trigger when server data arrives, we currently don't have a mechanism for outputting that packet to another destination.
