Hi Mirko,

Hm, I don't see that charon is actually able to find a new route to the
other host.  The last log entries are

Nov  9 17:32:55 moon charon: 03[KNL] interface ppp0 activated
Nov  9 17:32:55 moon charon: 12[KNL] creating roam job due to address/link change
Nov  9 17:32:55 moon charon: 12[KNL] getting address to reach

Could it be that the log is truncated?
