Hi , team: Will configuring filters through MDM create a new network? I analyzed that my security app was killed because it had created a network channel and continued to communicate, while MDM would create a new network, so the original channel of the security app no longer exists, so it received SIGPIPE. However, by configuring the network filter through code, it will use loadFromPreferencesWithCompletionHandler (Load the filter configuration from the Network Extension preferences.) and then saveTPreferencesWithCompletionHandler to save the network configuration. Therefore, using saveTPreferencesWithCompletionHandler: will not cause my app to be killed, is that correct? Is there a way to achieve the effect of using MDM to implement code saveTPreferencesWithCompletionHandler:?

In addition, 12.6.0 and 14.5.0 sometimes trigger SIGPIPE when starting the network filter, but not every time. How can I avoid triggering SIGPIPE?
