I'm attempting to get PPTP set up between a Mac OS X 10.3.3 client using
the VPN tool in Internet Connect and a FreeBSD 4.10-BETA box running mpd. 
I don't have a whole lot of experience with this, so it could well be I'm
doing something stupid.  However, the problem seems fairly consistent
across a number of tries.  It looks like something stalls during CHAP on
the FreeBSD side; on Mac OS X, it simply gets stuck in the "Negotiating" 
state for a while and then disconnects.  I don't know enough to know if
it's the server requesting authentication and the client not doing the
right thing, or the client sending auth data and the two passing in the
night... 

Here's the configuration file I'm using, with a slight password tweak and
address tweaks: 

default:
        load leigh

leigh:
        new -i ng0 pptp pptp
        set ipcp ranges 192.168.3.1/32 192.168.3.100/32
        set bundle authname leigh
        set bundle password "abc"
        load standard

standard:
        set iface disable on-demand
        set bundle disable multilink
        set link yes acfcomp protocomp
        set link no pap chap
        set link enable chap
        set link keep-alive 60 180
        set ipcp yes vjcomp
        set ipcp dns 192.168.3.1
        set iface enable proxy-arp
        set bundle enable compression
        set ccp yes mppc
        set ccp yes mpp-e40
        set ccp yes mpp-e128
        set ccp yes mpp-stateless
        set bundle yes crypt-reqd

The mpd.links entry is:

pptp:
        set link type pptp
        set pptp self 1.2.3.4           # would be external address
        set pptp enable incoming
        set pptp disable originate

Here's the error log -- it looks like there's some problem with getting
CHAP negotiated:
