Yes that's right:
the internal device is subnet 192.168.0.0,
the external device is subnet 192.168.178.0
Here are the complete network interfaces (sorry for the bad format):

Oh and by the way: nat from wifi interface to external interface is activated in pf also (thanks for your hint in the signature
)
