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. > For what I've seen the ip address on the ng0 interface disappears. 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. -- Alexander Motin
