Sorry for disturbing again. I investigated the problem a bit. Next my routes without VPN connection:

Ziel Router Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 2 0 0 wlan0

Here my routes when establishing the VPN connection and letting network-manager-openvpn manage the routes. Pinging Internet does not work with it:

And here my routes with the workaround described by Daniel. Pinging VPN LAN and Internet works with it:

My conclusion: the VPN server does not pass a default gw option but the network-manager-openvpn sets it! It should not set a default gw if it is not explecitly passed.

Hope this helps.
