Connect to local network with OpenVPN . Problem: Local IP address unset but adding route?

The goal =================== I do want to connect to some services (e.g. file server, IP camera etc) in my home network from my mobile phone by using VPN. I use Tomato Version 1.28 (shibby) on my Netgear WNR3500L v2 Router and I set up an OpenVPN server following the instructions here . The Problem ============== I then try to connect my OPO with Cyanogenmod 11.0 based on Android 4.4.4 by using the OpenVPN client. The handshake seems to work okay but then I receive the following error message on my phone in the OpenVPM app: [...] 2014-09-25 21:09:07 MANAGEMENT: CMD 'needok 'ROUTE' ok' 2014-09-25 21:09:07 Local IP address unset but adding route?! This broken!

What setting am i missing? Why can't I connect to my home network via VPN?
