Have you done a full update of wheezy on your pi? I suspect it may have something to do with the libc update. I know Ubuntu and Mint's libc breaks apps, I hope pi isn't doing the same with Raspbian.
(and ttl inherit nopmtudisc) So I'm wondering how you get mtu 0 there.
mtu 0 is auto discover. This is forced in the updated wheezy. I don't know if it's the same with jessie or not.
Are you using an other command line to start your tunnel interface?
Nope. This is a new forced config with raspbian from what I've seen. You can still change MTU but you can't change ttl. If you haven't updated... DONT!
