Sorry for the late update, I've been busy with work.
Ok after following the link to the guide I found it was the same guide I already tried, in case it had been updated in any way I tried again but no luck.i tried removing and adding my both my PS4 and pro but still no joy.
When I set up my pro at xmas and moved my old ps4 to my bedroom the geo filter was working but my pro had mod nat type,I tried to swap or add my pro to my by router online but for some reason it would only let my chose the old PS4. So what I did was swap the I.P and I think subnet mask around and it worked. I then got open nat on my pro that's in lounge my gaming setup and the old PS4 in my room for sky Netflix etc went back to mod nat type.
But since then my geo filter not worked,I also tried reconnecting to the net using automatic/easy instead of manually but still no luck.
I'm lost,I hope I have explained well enough for someone to do understand what I've done.
