I hope they will be merged sometime - it would be easier to set up routes
if you could specify the interfaces (in addition to addresses).

You're right.. my ppp0 netmask is 0xffffffc0 instead of 0xffffffff
(which it should be, right?).  I guess that's why NetBSD didn't get my
idea.  My fault. ;)  (I managed to set the route by taking the ppp
connection down, setting the new route, and bringing ppp up again, but
that was a m$ way of doing things ;)

Thanks for the help,
