That line can say one of

  tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
  tun0: flags=8050<POINTOPOINT,RUNNING,MULTICAST> mtu 1500
  tun0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500

depending on if it's been configured or not.  Assuming you have an 
entry for /dev/tun0, your best bet is to get the latest ppp from 
http://www.FreeBSD.org/~brian.  I've heard of this before, but it 
doesn't happen with newer versions of ppp....
