    mask 255.255.255.255
    pool TEST_POOL
    profiles {
        TEST-ISO { }
        profile_mblb { }
        tcp { }
    }
    rules {
        TEST-3
    }
    serverssl-use-sni disabled
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    translate-address enabled
    translate-port enabled
    vs-index 2
}

my: mblb

ltm profile mblb profile_mblb {
    defaults-from /Common/mblb

when CLIENT_ACCEPTED {
  log local0. "[IP::client_addr]"
  #LB::context_id "server"
  TCP::collect
}
when CLIENT_DATA {
  if {[binary scan [TCP::payload] S length] == 1 && [expr { ($length & 0xffff) +2 }] == [TCP::payload length]} {
    log local0. "This packet length meets header length value : Header value : [expr { ($length & 0xffff) }] / Packet Length : [TCP::payload length]"
    TCP::release
    TCP::notify request
    TCP::collect
  } else {
    
    log local0. "This packet length doesn't meet header length value... this is not a valid ISO 8583 packet. reject the connection"
    reject
  }
}
when USER_REQUEST {
  TCP::notify response
  LB::detach
}
