Configuring Trusted Network Detection
The Apple Trusted Network Detection (TND) enhancement to the iOS Connect On Demand feature is available in
iOS 6. TND results in the following:
Can be used only with Connect on Demand.
Extends the Connect on Demand functionality by determining whether the user is on a trusted network.
Configured with the iPhone Configuration Utility.
Used for Wi-Fi connections only. When operating over other types of network connections, Connect on Demand does not use TND to determine whether a VPN should be connected.
Connect On Demand starts a VPN connection whenever a user tries to access a destination with a hostname
specified in the domains list. For example, if
*.example.com is in the Always Connected list, when a user
internal.example.com, the client starts a VPN connection regardless of the network to which
the device is currently connected. TND compares the VPN and local DNS servers and DNS suffixes to determine
whether to use Mobile Connect and dial the VPN, as shown inthe Trusted Network Detection according to

|DNS Suffixes||DNS Servers||Login|
