Capturing packet to analyse:
There has only the data of syn for the capturing packet information. The server doesn’t process the data which has been send by us
Why doesn’t process the data of our equipment?
We can analyse the capturing packet information in the normal situation and find the source port(the port of hundred thousand)of request is bigger than the source port (the port of thousand) of sending
We try to modify the port of source nat range:
hrp nat ports-segment secondary //the cost range of port number is 33768~65535.
Then we have a test, the problem has been solved, it can access normally
