> Model: R7000P|Nighthawk AC2300 Smart WiFi Dual Band Gigabit Router

   "R7000" and "R7000P" are different.  Which is it?  Firmware version?

> Mon routeur affiche 2 adresses IP identiques pour deux NAS différents

GT> My router displays 2 identical IP addresses for two different NAS

   "displays" how?  What are these two IP addresses?  What are the "two
different NAS", and how are they configured?  Static?  DHCP?

   Any useful information at all might help.

   History?  Is this a new installation, or some kind of change to a
previously working installation, or what?
