This bug is due to a failure in handling router advertisments. According to RFC 4861 (page 20) a _Cur Hop Limit_ set to 0 means, that the Hop Limit is unspecified. Ubuntu 15.04 takes this literally and sets HL to 0.
Fortunately my router provided the option to set this field to a manual value, altough i suppose this is not the case for most routers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1450066 Title: IPv6 hop limit set to 0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1450066/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
