Where I said before that the packet vanished, I now know that it goes out through the WRONG ethernet interface (tcpdump tells me that), although there is nothing in the local or main routing table that suggests to do should do that. If I request the destination gateway with "ip route get" for the respective destination I get the CORRECT ethernet interface. Evidently the de-tunneled packet doesn't get far since the destination host is on a different physical LAN.

Have you tried compress=no? If it works with compression off, then
that may be a kernel bug.  Unfortunately I haven't got around to
looking at this yet.
