Route 10 and Nest WiFi Gen2

Yes, I know… lol It’s horrible but I’m stuck with Nest WiFi until the AP7-Pro is available, hopefully soon!

Until then…

I have a problem :slight_smile: Go easy on me, I messed with port forwarding, routes, creating 2 VLANs and connecting them via static route, etc. and nothing worked. Only thing I haven’t tried is subnetting to 255.255.254.0. I have a few fixed IP WiFi clients and I’m trying to avoid re-configuration.

Problem: Route 10 connected clients, can’t talk to Nest WiFi clients. Essentially I’m double NATed.

Setup:

  • WAN 1 not in use
  • LAN1 2.5Gbps switch with other clients (great we can talk!)
    • DNS Server: One of the clients is a docker server hosting AdGuard as DNS proxy
  • LAN3 My personal PC with fixed IP
  • LAN4 not in use
  • WAN2 SFP+ PON on AT&T
  • Route 10 is pretty much default leveraging VLAN 1 192.168.50.0/24
    • Primary DNS: AdGuard server above
    • Secondary DNS: 1.1.1.1
  • Nest WiFi WAN is connected to LAN2 on Route 10
  • Nest WiFi sees the route 10 as a WAN
  • Nest WiFi LAN is using 192.168.51.0/24
  • Nest WiFi can’t be set in bridge mode, it’s an automatic setting and since I’m using 4 APs in mesh, it automatically defaults to (NAT) mode
  • Insult to injury Nest WiFi automatically blocks ICMP traffic incoming from the WAN, pinging anything from Route 10 is a fail.

Ideal State: I just want my route 10 and Nest WiFi clients to be friends and talk to each other until I can toss the Nest WiFi in the garbage when AP7’s come around.

I researched this a bit.. I don’t think you are going to have a way out of this unless you run wires to each one of the nest wifi’s. Reading their docs it looks like they will only work in router mode while doing a wifi mesh(that is kind of weird/crazy). That means it will do it’s own DHCP server and everything and yeah it’s probably not going to work. Sorry..

I think you’re right.

From what I’m seeing, the Google Nest WiFi router is inflicting “NAT Isolation”. This makes sense since my WiFi traffic can access Route 10 traffic but not the reverse.
