That's a known limitation and the result of design decisions made a
long time ago. I rather suspect that changes are on the wish list,
but IPv6 development will be taking priority at the moment.
it also affects people wanting to run it on routers connected with
(eg) PPP links over WAN lines - where it doesn't work because certain
assumed facilities (broadcasts I think) aren't present.
