Existing Router and Orbi setup

[BSD-Kurt]

I have an existing firewall/router, not a wifi router but a unix router that does NAT, DHCP, UPNP, firewall, vpn, etc. I would like to replace my existing two Nighhaws R7000's that are both in Access Point mode with three Orbi's for better handoff and coverage when walking around the house and basement as well as hopfully better speed.

Can all Orbi's be setup in Access Point mode mode (no second NAT, no DHCP) and mantain handoff and speed features or does one Orbi need to do a second NAT? All three Orbi's will be connected via wired backhaul - no mesh needed.

Pointers to instructions or kb would be appreciated.

Yes, there is a AP mode setting on the RBR router.

Single NAT is preferred.

Be sure when trying to configure and connect wired backhaul, use non managed switches. Orbi seems to not like Managed switches currently. Something about IGMP Protocols.
