And I mean to make this side of things easier to do, but I haven't gotten the time yet :-( As a side note, I am now using a rather obscure PPPoUDPoPPPoISDN arrangement from home so that I can do link compression on the top PPP. I'm also trying to conceive of ways to make this sort of thing easier to do. I should be able to do a multi-link version of this too, but the last time I tried to explain how to do this (see usr/share/examples/ppp/*span-isp*), I don't think people really embraced it fully :-I FWIW, for those of us in the ``connect-to-isp'' market, I'm currently working on getting MPPC/MPPE working in ppp.... > hellmuth > -- > Hellmuth Michaelis Tel +49 40 55 97 47-70 > HCS Hanseatischer Computerservice GmbH Fax +49 40 55 97 47-77 > Oldesloer Strasse 97-99 Mail hm [at] hcs.de > D-22457 Hamburg WWW http://www.hcs.de -- Brian <brian@Awfulhak.org> <brian@[uk.]FreeBSD.org> <http://www.Awfulhak.org>; <brian@[uk.]OpenBSD.org> Don't _EVER_ lose your sense of humour !
