I'm testing out npppd as a termination device which is being fed from

gives up:
In this case, npppd assumes the LAC is using "Proxy LCP and
Authentication" AVP in RFC 2661.
Is it possible to force npppd to treat it as a non-dialin tunnel?

Do you have the "dialin-proxy" message before these messages? If you
have, I would like to see it.
The only message ppp related prior to those is:

Those AVPs don't seem to be requested by the LAC.

The LAC seems to be starting CHAP without LCP. The problem seems to
be come from the LAC.
If mpd has settings about "proxy LCP and authentication", I would like
you to try them.
mpd doesn't have the ability to generate Proxy auth AVPs, I currently
use both mpd and others without proxied avps, afaic it isn't breaking
rfc to restart lcp at every point (which is how I work things currently)
How difficult would it be to add a config option to always restart lcp,
or maybe just if proxied avps aren't there?
