Anyone used the built-in PPTP VPN client on OS X to successfully connect to
m0n0wall v1.0?

I've got it set up to the point where it begins negotiating, pauses for a
while, and then reports that the PPTP server closed the connection.  The
only suspicious logged line on the m0n0wall side is:

   mpd: [pptpc0] error writing len 42 frame to bypass: Can't assign requested address

which seems odd, as the LAN interface for the firewall is:

          <if>sis0</if>
          <ipaddr>192.168.1.50</ipaddr>
          <subnet>24</subnet>

and the pptpd config looks pretty much smack in the heart of
192.168.1.0/24:

    <pptpd>
        <mode>server</mode>
        <redir/>
        <localip>192.168.1.51</localip>
        <remoteip>192.168.1.208</remoteip>
        <user>
            <name>YYYYY</name>
            <password>xxxxx</password>
        </user>
        <radius>
            <server/>
            <secret/>
        </radius>
    </pptpd>

Anyone had any success with this?  I'm not quite sure where to start poking.
