I am trying to get to following setup work on my Raspery PI with XBIAN.
I have an UPnP server running (which uses multicast) on ip 192.168.1.41
and I am trying to configure OpenVPN as bridge (because of multicast).
I want to run the android app OpenVPN Setting
https://play.google.com/store/apps/details?id=de.schaeuffelhut.android.openvpn
which supports tap.
My problem is, when i run the bridge-start script, that my raspberry loses ssh connection after short while. Before it crashes I can connect with my Android or Windows OpenVPN client, but don't see my UPnP Server in my UPnP apps.
My other try was to run OpenVPN as tun and use smcrouter to route multicast traffic. Unfortunatly does the raspberry kernel not support multicast routing. (Is this a problem for the OpenVPN bridge too?).
