Ahem, yes.  My brain was just getting to that bit - the default route
on waix breaks outgoing connections which aren't routed through waix,
so we need to individually route those.  This doesn't just include
130.95.*, but also cygnus, bits of it.net.au, and the other
universities.

This is why we need a router device in betwen UCC and UWA which can do
this sort of munging.
