source ip for clone-pool syslog

Quick question trying to duplicate traffic to go to two backend syslog servers trying to get the cloned traffic to send source client-ip and not the self ip of the f5 what is the best way to go about this?

below is the current iRule being used to clone traffic.

when CLIENT_ACCEPTED {
  snat [IP::client_addr]
 set hsl [HSL::open -proto UDP -pool syslog-pool]}

when CLIENT_DATA {
        HSL::send $hsl [UDP::payload]
}
