Hi, thanks for the feedback.
QQ, just to clarify. Your "Yes" means this should be supported but performance could be an issue, right?
Is our approach to using an app activated content filter reporting to a daemon connected via XPC unsupported?
Yes.
You have to be careful about performance here, but the basic concept is sound.
I have been able to test the disabling the built-in firewall and after a restart to flows are received normally by our content filter. This would seem to confirm we're hitting the issue reported by others (FB15699871).
I'll work on preparing a bug report and will post it here.
Thanks for the help,
Dave
