Hi,

here is my view of things (although I am no network professional):
it DOES actually route it, but to the wrong destination.

The broadcast on pp-link's net would be 192.168.2.255 I assume
(you did not specify the netmask).
192.168.2.200 does not match this, so the next possible route is used,
and that is:
> 192.168.0        192.168.0.3        U          39   368887  en0

Why ? 192.168.0.0 is the net containing all 192.168.x.y adresses with
192.168.2.200 being the ONLY exception. So all broadcasts are sent
through "en0".

The added route creates another exception for the 192.168.2.0 net,
and so the broadcast is routed correctly.

Does this make sense to you ?
