Google Wifi hack: Connecting to old static IPs

Google Wifi Router

Are you setting up a new Wifi router and have a bunch of devices with static IPs? When converting to the Gogle Wifi router, I discovered a cool hack to get to your devices with their old IP addresses even though the router is using a new subnet or IP range.

The Google Wifi is a cool way to blanket your home with wifi. Place multiple nodes around your home and the create a mesh network among the nodes. Each node has multiple ethernet jacks. Only the primary node needs to be plugged into your router. On the secondary nodes, the ethernet jacks allow you to connect ethernet devices to the network directly. Essentially the nodes act as if they are wired. You can plug a printer or camera or desktop computer into the nodes. One drawback to the Google Wifi is that you can’t connect them using a wired network. This is contrast to the competing eero system which allows the nodes to be connected via a wired network as well as using the mesh network.

What about those static IPs?

One of the challenges to using the Google Wifi is you need to convert all of your devices to the new network. In my case I was using the private subnet 10.1.1.x. If you’re using DCHP this isn’t a big deal, but in my case I had a bunch of cameras with fixed IP addreses like 10.1.1.60 so I could connect to them directly and also setup port forwarding for external access. My main reason for doing this was so I could easily connect to the cameras directly. If you use DHCP, the IP addresses of the cameras will change over time and if you want to connect to them, you need to rediscover the camera’s IP address, which can be a pain.

How to do port forwarding with eero

eero wifi system

The eero wifi system is really quite amazing. It lets you blanket your home in wifi and manage it with the eero app. You can do lots of neat things, like pause the internet for different devices or manage the network even when you’re not home.

Normally to do port forwarding to your IP camera, you need to configure the camera to have a specific IP address, then go to the router and add tell it to forward external ports to the internal ports on that IP address. eero takes a different approach.

However, if you don’t want to do port forwarding at all, you can simiply use Sensr.net and have your camera push to Sensr.net.

There are still some reasons you might want to do port forwarding, so here’s how it works with eero:
