OR KNX - VPN required for access over WAN?

Hello,

I´m new to OR and want to test it with my KNX System.

My KNX System is conneted to the Internet using a 2G / 3G Router. It
Controlling my System with OR KNX Lite works fine as long as I am connected to Local Network (Wlan)

But it fails when I try to connect from Outside (WAN) with my iPhone over a 2G / 3G connection.

I have on my iPhone an other KNX monitoring app - with this app I can connect to my System.

So my Question is...

Do I have to use a VPN connection to my KNX System when I want use OR KNX Lite on iPhone from the "outside world" ?

    The full version of OR KNX can do without VPN (according to some users), however you don't want to do that - KNX has no user authentication, i.e. every script kiddie scanning for an open port 3671 can control your house So use of VPN is strictly encouraged.

        Hello Jörg,

        I have now the Full Version of Open Remote KNX Version 1.5.2

        It does not work over WAN without VPN

        Other KNX Software like ayMonitorKNX on same iPhone or ETS on a PC is working without problems using the same WAN connection.

        it seems for me that Open Remote KNX Version 1.5.2 works within the same Net only.

        Do I have to open additional Ports

          Dear Richard,

          due to the security implications, the non-VPN connection is neither fully tested nor (possibly) fully implemented. However some users reported that they have used it successfully. Imho you need the following: a) set the correct gateway in the Ethernet-KNX-gateway, b) forward port 3671 in your router.

            Just a new status info to this subject...

            I have changed the APN in my iPhone. Now my iPhone gets a real IP address.
            With this new configuration I CAN connect with Open Remote KNX to my EIB System.

            I´m using a SIM card from the same provider for my iPhone and my UMTS Router (.. connected to my EIB system)!

            This may be help users with similar Problems...
