I'm not really competent to wade through the log without spending a bunch of 
time doing additional reading. Just in case it helps, perhaps you could 
answer a few questions:

   - What exactly happens after you see the user authentication 
   diagnostic? For example, does the WXP client think the connection is live 
   for any length of time at all?
    - Are you using the PPTP service built into the m0n0wall or 
   redirecting from the m0n0wall to some other PPTP server? 
   - Do you have a username and password (and possibly a user-specific IP 
   address) defined or are you using RADIUS authentication?
    - What PPTP server address have you defined? 
   - What remote address range have you defined? 
   - What IP addresses are you using internally (on the LAN)?
    - Are you requiring 128-bit encryption on either side or both sides?
