NAT Type problems with Wired Connection. Both Type 2 and 3.

So heres my issue. Wired ethernet from my modem into the PS4.

PS4 Test Internet Connection states NAT Type 2.

However when in Modern Warfare Remastered, NAT Type according to their network status is NAT Type 3.

Could not join any session with my friend in MWR because of this NAT issue and would like help to get this resolved.

However, when I connect my PS4 via WiFi through my router and not modem my NAT type is both Type 2 and can join my friend in MWR fine. I suspect I need to change something but not sure what.
