I've got a FreeBSD box at my provider's site which I dial into from my
SunOS box at home, to connect my small home-net; no stand-alone
routers.

I've been trying to coerce pppd into installing the default route
using the /etc/ppp/ip-up facility, but although the  pppd runs ip-up
with effective UID root, if ip-up is a script, FreeBSD squashes the
root privs (that, or pppd uses getuid() rather than geteuid(), still
looking). I guess I could use a SUID perl script or some C code but
this seems too simple to justify that...

I did bring gated up on the FreeBSD box, and got a config written
(first time user!) which seems to establish the /28 route when I ppp
in, and tear it down when I disconnect. Still have to do the same on
the SunOS side at home. The docs seem to indicate it does VLSMs fine,
with other RiPv2 routers. Guess I'll find out :-)

Thanks.
