I've looked at _updown, but there's no obvious (to me) modeconfig 
variable. The closest thing I found was this in uprule()

  # virtual sourceip support
     if [ -n "$PLUTO_MY_SOURCEIP" ] && ["$PLUTO_MY_SOURCEIP" != "no" ]
     then
         addsource
         changesource
     fi


How would I modify _updown to use the modeconfig'ed virtual IP?
