Hi Simon, Perfect! I will rebuild the debian package from the snapshot and try out. As far as I see, you have not yet made the RA_INTERVAL configurable (only for the unsolicited advertisements), so I will patch this, too. But in any case, I can raise the lifetimes now, so the problem will appear later.
