I got it now. In said example carol and dave can connect to winnetou via VPN to moon by the way of moon's NAT. For me the obstacle was, that the IP of winnetou must be part of leftsubnet in moon's ipsec.conf.
My actual objective was to set up at my home-server aVPN gateway into the internet, so e.g. in public wireless environments I can effectively prevent MITM sneaking into my traffic. For this to work, leftsubnet must be set to the whole internet, i.e. 0.0.0.0/0.
FARP is not needed for this. FARP would be needed to access other clients in the local network.
