I tried again the ping6 (without specifying the source HIT) and first it said: connect: Resource temporarily unavailable Then again (just 1s after)... and it worked!!! O_O Do you have any explanation for this?
I believe that for example with tcpdump you can see that it does the HIP base exchange at the first time (connect: Resource temporarily unavailable), and when pinging again after the HIP base exchange it works. Policy-sleep patch should correct this in some kernel versions. -Teemu Väisänen
