When using an ADN network in an ADN Manager/Peer environment you can use the option Web Gateway on the ADN Manager.

When you enable the Web Gateway option on the Core SG unit this will mean that the Peer HTTP traffic will be passed to the internet via an Explicate ADN tunnel to the Core ProxySG and then out to the internet.

Because the connection is explicate between the Peer and the Core this means that the Core will see the sending IP as the Peer proxy IP and not the client PC. The connection from the Core ProxySG to the OCS will be subject to NAT on the Core ProxySG so it will be sent with the IP of the Core ProxySG device.
