VPN breaks PVR Function

When I enable my VPN on my Shield TV, everything works in Kodi with the exception of the PVR functionality. I assume that since the VPN app in on the Shield TV box, the pvr doesn’t know the outside ip address(it is configured to use a local address). How do people deal with this issue? I don’t want to have it resolve to an external ip address for various reasons. I am using VPN unlimited.
