There are possibly two routes you could take. Looking on Google Earth there is a service road opposite one of the OKW entrances that will take you to the POFQ car park (I don't think this is gated, but you never know until you try the actual ground route). The other option is to follow the path across the golf course. This takes you to the bridge between POFQ and POR. Again, I have never used it so can't really comment on its suitability.
...but I'm sure someone on these boards must have attempted it.
