You could try this:


when CLIENT_ACCEPTED {
  if { [IP::addr [IP::client_addr] equals 172.19.10.70] } {
    use snat snat_a_IP
  } elseif { [IP::addr [IP::client_addr] equals 162.66.195.95] } {
      use snat snat_b_IP
  }
}
when HTTP_REQUEST {
  if { [IP::addr [IP::client_addr] equals snat_a_IP] } {
    pool LMS-lms.lnh.bislab.pwj.com.80 member 172.19.10.70
    log "hit member 172.19.10.70"
  } elseif { [IP::addr [IP::client_addr] equals snat_b_IP] } {
      pool LMS-lms.lnh.bislab.pwj.com.80 member 162.66.195.95
      log "hit member 162.66.195.95"
  } else {
      pool LMS-lms.lnh.bislab.pwj.com.80
      persist source_addr 10800
      log "hit pool"
  }
}

This, of course, is assuming the client IP is snatted before the HTTP_REQUEST event occurs. Not tested!
