There may be couple of reasons for such behavior. Actually i was trying to figure out it one-by-one but i could have done it in one go (my mistake).
With CMP enabled state, F5 may change source port to keep the client-side and server-side traffic on the same TMM. Here F5 ignores Preserve setting.

thanks to Mayur!I think as you said, CMP may be the real reason of all this. I think I can insert the source address and source port in the http header, and get the source port of the client by irule. Thanks again!
when HTTP_REQUEST {
HTTP::header insert Cliet_IP_port [IP::client_addr]:[TCP::client_port]
}
