Can't help with the first part but
SCNetworkInterfaceForceConfigurationRefresh is used to renew a DHCP
lease

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.
