So I want to set up my network like this and just looking for help how. If I set up the Netduma turn off WiFi and turn off DHCP and instead assign a static IP to those devices (only 3). what could I do about not getting double Nat on the Netduma. Also because there’s two routers will the Nat on the normal router effect the duma?
Your modem is a router too. Do the other routers support Access Point mode? That would eliminate double NAT.
