Disable NAT on Nest Wifi Router

[jesmith4]

I need to disable NAT on the nest Wifi. Bridge mode is not an answer as I don't want to disable mesh.

This is my topology:
ISP<-->Firewall <-->Nest Wifi Router<-->Mesh and Switch <--> Wired and wireless devices.

I need to see the end user IP addresses for proper firewall policy configuration and logging but currently the Nest hides all end user IP addresses behind it's WAN IP. I need to disable this. Is it possible?

Not possible. I've heard of jank workarounds that involves setting the subnet mask to not allow any devices to get IPs from Nest Wifi, then set DNS to be the router in front of it or something like that. Google "nest wifi" and "pi-hole" or "custom dhcp". Example hit:

Hi jesmith4,

I just wanted to jump in real fast to see if you saw olavrb's reply and to see if you still needed some help on this or if you were able to get it sorted out. If you are still needing some help, just let us know and we'll be happy to continue helping.

Thanks,

I guess. It doesn't really answer why I can't make these changes. I realize most users are basic plug-and-play with little networking knowledge. Not all of us are that way though. It would be good to have some options for more advanced settings allowing for more complex network setup.

I understand the disappointment by the lack of feature, jesmith4. I can actually pass along to our teams your request to see this functionality added to the Nest WiFi options. Those requests are regularly reviewed and help shape future iterations of device firmware and hardware. I'll pass that along now. I do think you're on the right idea about plug-and-play being favored, but at times users need a bit more control, like I can see you do here. I appreciate the input on that.

Thanks,

Jeff
