When running the default n3iwf test case, it is found that the last step in the use case sending ICMP package from 188.8.131.52 to 184.108.40.206 is unsuccessful.
The following abnormal information was found during the trace log tracking test process. From the log feedback results, the exception occurred when UPF tried to unpack the gtp-u packets sent by n3iwf, which caused UPF not to respond to n3iwf.
I didn’t modify the logical structure of the source code, just the IP information related to the test environment.
Would you pls help? thanks!
