The config is not different.
You just need to use 'client nat' or PBR to force response from server to got through the CSM as well.
If you want direct server return, you need to use 'no nat server' on the serverfarm, which means the servers needs to be configured witht the same loopback ip address equals to the csm vip.
For tcp traffic, you will also configure the command 'unidirectional' under the vserver to inform the CSM not to expect to see the server traffic.
