External Captive Portal in IC2


i was checking new features that came with latest IC2 release (9 Feb) and I noticed that there is an option to create external CP on IC2. How do I adapt CPs destined for devices such as MAX or Balance to work properly on IC2? Do you have any manual like the one you released for creating a CP for previously (it disappeared when the knowledgebase portal was replaced with the forum)?

Would be thankful for any advice :slight_smile:
