routing outages miredo (teredo) -> HE tunnel

[yanosz]

Hello,

I'm using miredo (on OS X, using MS teredo servers) in order to connect to an he tunnel endpoint. Furthermore, a routed /48 is assigned at the endpoint, while routed::1/64 is assigned to a tap0 interfaces.

ping6'ing / traceroute6'ing the tunnel endpoints works:

while route::1 has temporary, non-deterministic outages:

For some reason (in the non-working example), packets didn't go beyond localhost. While pinging the tunnel endpoints works at the same time...

Do you know what's wrong here? Is it a miredo issue?

Thanks,
Keep smiling
