[Kea-users] Change in offer packet

Thomas,

This is not configurable, although it could be because RFC2131 says that
server SHOULD send to broadcast address (rather than MUST).

The only thing I can suggest to you is to use a hook library that clears
the broadcast flag in all incoming messages (in the packet4_receive hook
point).

The bad side of things is that you need to create a hook library. The
good thing is that it is trivial.
