what i mean is the list of received hna4-announcements (>status > olsr
or something alike).

the default route only lists the next hop in direction to the gateway.
that is why i was asking if NEW is 'behind' OLD seen from most nodes.
there are two cases:
1. OLD still broadcasts hna4-announcements for 0.0.0.0. in that case
dyn-gw-plugin would be the place to look.
2. OLD does not announce hna4 anymore, nor are other nodes of the
opinion that it would be doing so. nevertheless, packets crossing OLD
are sent via WAN instead of being forwarded to NEW. in that case it
would be an iptables issue or something the like.
