I am trying to setup my FreeBSD 4.1-STABLE server to accept dialups from
my Windows laptop. For a few months now I have had no success (wasn't in
that much of a rush), but recently I've had a great need for that
arrangement so I've been trying again.

Currently I'm using mgetty + AUTOPPP to start pppd on dialup, which
appears to be working (mgetty calls pppd successfully). However I have no
been able to get pppd to complete the PAP auth. My modem on the FreeBSD
box is an internal USR Courier with latest Flash bios on com port 1,
cuaa0. My server address is 192.168.1.1, and I'm trying to give the
Windows laptop an address of 192.168.1.11.

Quick questions: 1. Why is base still using pppd version 2.3.5? Seem
rather stale. 2. Is the main question, refering to the following log:

From what I can tell of the log, it seems like the FreeBSD box requests
pap auth from the laptop, and the laptop sends back a request for
callback, FreeBSD rejects the callback as it should and makes another
attempt at pap auth, but the laptop seems to keep ignoring it and keeps
sending callback auths. This cycle continues, until eventually it times
out.

I am at a lost as to what to do from here on out, and am hoping members of
this mailing list would be able to help me solve this issue. The FreeBSD
box is running ipf with a restrictive filter, ipnat, and djbdns. If more
information is required, please let me know and I would gladly provide it
if it would resolve this issue.

So far none of the Windows machines I have have been able to connect to my
FreeBSD dialup server, all have the same results.
