Tcpdump on ng0 interface should display traffic inside tunnel. It also 
may be interesting to look on internal interface as tcpdump is able to 
decode PPTP packets.

This may be significant. Configure syslog for logging mpd messages, it 
should give you information about why IP disappeared. Probably it 
happened in result of some error. Also look to the messages logs, there 
may be something interesting.
