MACOSX 10.9.3 cannot ping local gif0 v6 address

[shinydeb]

I am unable to ping my local v6 address on my machine & obviously cannot get my v6 tunnel working. Has this happened to anyone else? Here are some snapshots. :-[

MTU is low, are you sure it's right?  (Not that it would affect local pings)

On some versions of BSD I had to use GIF1 instead of GIF0, you may try that.

Hello everyone,

Same problem for me :

gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
   tunnel inet 192.168.1.12 --> 216.66.84.42

   nd6 options=1<PERFORMNUD>

I even unplugged my router Netgear WPN824v2 for a test and configured a DMZ with 192.168.1.12. Impossible to obtain a connectivity with IPv6 and Mac OS X (Maverick).

Only this command does work :

root# ping6 2001:470:1f12:946::2

But http://ipv6.whatismyv6.com/ gives me like result "Page Web inaccessible"

error code : DNS_PROBE_FINISHED_NXDOMAIN.
DNS resolution failed.

Thanks in advance.
