How to Divert traffic based on Self-IP's not on basis on SNAT

Thank you so much Kevin, so just to clarify myself:

SNAT is for response from the servers While SELF-IP is for request from the remote end (client).

So, as we are planning to segregate the traffic based on request from the client, so editing the irule by replacing snat with selfip, kindly guide whether this is correct:

when CLIENT_ACCEPTED { if { [class match [IP::client_addr] equals my_ip_datagroup] } { selfip 1.1.1.1 } else { selfip 2.2.2.2 } }

Thanks and Regards Parveez
