Try this, if the client is on the same subnet it will not snat, if client is NOT on the same subnet, it will snat. Change [pool/automap/none] as needed:

when LB_SELECTED {
  if {[IP::addr "[IP::client_addr]/24" equals "[LB::server addr]/24"]} {
   snat [pool/automap/none]
  } else {
   snat none
  }
}
