I sent this yesterday to macnetworkprog, but I wonder if this list might reach more people who've encountered the issue before...
--- I'm working on an iPad app to control a device. In one possible configuration, the device hosts a Wi-Fi network and the user connects the iPad to it. The device has a DHCP server and provides an IP address and subnet mask to the iPad, but does not provide a Router or DNS or other information. We are able to successfully make TCP connections to the device over Wi-Fi. If the iPad also has a cellular data plan, we want to connect to our server (this is a server in the cloud, not the device) via that cellular data connection. But the SCNetworkReachabilityFlags I get back are 0 (unreachable, not WWAN). Attempts to connect to our server fail. Attempts to use Safari to connect to the internet fail. Is there something about what our device is providing via Wi-Fi that prevents the iPad from figuring out how to route traffic? Is it not possible to split network operations this way? I thought it could do this, and this is critical to our product's ease of use.
