I have an iPhone application that I would like to use to access a VPN. I've configured the VPN through the Settings app on the iPhone, but my app still can't access the VPN to get data. A similar Mac application I developed worked without issues through this VPN.
The connection for VPN used is "PPTP". In Safari on the devices, typing the url as
http://vpnip shows a page with IIS.
Is there anything I have to programmatically enable or configure inside the app to look for the virtual private network?
