Would there be a way for a 3rd party to trigger a network reachability
callback?
The situation is the following one:
Let's say I have a 3rd party firewall running and it's blocking network
access.
In another user application project, during initialization I check the
connection flags with SCNetworkReachabilityGetFlags and then install a
SCNetworkReachabilityCallBack through the usual APIs.
The call to SCNetworkReachabilityGetFlags correctly sees that the
network is down.
Then I change the 3rd party firewall settings and allows all network
communications.
The problem is the reachability callback is not called as it would be
if, for instance, I had un-plugged the Ethernet cable.
So:
- is there a way to trigger a reachability callback?
- is SCNetworkInterfaceForceConfigurationRefresh what is supposed to be
used? I'm not sure it is from the documentation.
