I am experiencing the same issue. After a while trying to understand why my v4tunnel was not coming up, I realised that NetworkManager was screwing up, again.
I also have the managed=false statement, which is clearly ignored. But I managed to make it understand by adding this (requires manual synchronization of interface names, which sucks): # cat NetworkManager.conf [main] plugins=ifupdown,keyfile dns=dnsmasq [ifupdown] managed=false [keyfile] unmanaged-devices=interface-name:he-ipv6 At least, with this it stopped messing around with my tunnel. -- Martín Ferrari (Tincho) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
