Orbi wanting two public IP's via DHCP

What is the Mfr and model# of the ISP modem/ONT the NG router is connected too? Built in router here by chance? 

Any Orbi our single NAT router only gets/requires 1 IP address from any kind of DHCP service, WAN or LAN. Orbi AC doesn't support LAG either. Orbi AX does where you could have two WAN IP addresses aging to the RBR.

Hello,   We are trying to help a customer that owns a ORBI router device.

When doing a packet capture on the PUBLIC facing interface from the ORBI we see that the ORBI wants two public IP's.

If we limit the number of public IP's that the ORBI can use, then the ORBI doesn't work.

 

Why does the ORBI need need multiple public IP's

How do we make sure the ORBI will operate with a SINGLE IPv4 Public IP  that is issued from us (the ISP) via DHCP

 

NetGear ORBI's are the only CPE on our network that we have this issue with.  

 

Note:

1. This is PUBLIC IP's, not RFC-1918 addresses on the internal or LAN side

2. This has NOTHING to do with DNS

3. NO We do NOT provide a router.  The customer is connected via a P2MP microwave system (not wifi) as a OSI Layer 2 link.

    Our aggregation router issues public IP's via DHCP

 

Thank you
