The NATStream Function Does Not Take Effect on the CE6851HI

Hi fufufuf!
The possible causes are as follows:
1. The destination port number of the NATStream flow sent by the CE6851 is different from the receiving port number of the NTA.
2. The NTA device incorrectly identifies NATStream flows.
Suggestions:
NATStream packets are UDP packets, and the port numbers at both ends must be the same. The default values of devices from different vendors may be different. Pay special attention to the default values during deployment.
NATStream servers of different vendors may identify NATStream flows by default. During interconnection, ensure that NATStream flows are identified based on NATStream flows.
