Impossible to ping6 end of tunnel
« on: August 05, 2017, 06:30:48 AM »
Dear all,

First, I would like to congratulate you for the hard work around IPv6.

I am behind fiber in France and my provider (RED) does not provide IPv6 (yet).
So i set up an IPv6 tunnel under LEDE (a reboot of OpenWRT).

Access-point is in Paris, as I am French.

For some reason, the tunnel stopped working and now I cannot ping6 end-of-tunnel.
What should I do to start debugging?

Kind regards,
Logged

Has your ipv4 address changed?

No, I could verify that.
All settings are perfectly the same.

Fixed, thanks.

There was a small problem with my configuration:

option 'mtu' '1424'   
made the trick.

Many thanks.
