Christian,
The errors below seem to show that tunnel packets are arriving truncated from
the peer. The error specifically means that the packets arriving are smaller
than the IP header size, therefore they could not be valid IP packets, and are
thus rejected by the TAP-Win32 driver.
It would help to see what's going over the wire, using --verb 6 or higher, or
tcpdump.
