I am trying to use the example of the network extension. Now I have completed the necessary profile configuration and other content. After I try to run, a corresponding small window will pop up, but no matter how long after I click start, no matter what connection I send, it does not respond and display. I would like to know how to open a connection on the port being filtered? And then to make the SimpleFirewall work as expected?
I’m not sure what’s going on in your specific case, but there’s some general advice in Debugging a Network Extension Provider.
Share and Enjoy
