In my home I have my AT&T fiber running into their router (I will call this A). A is connected to an EEros router throughout the house as wifi (I will call this B). A also has its own wireless network but for 99% of the network everything is connected to B.
So here is my question:
I have a printer connected to the Eeros network (B) but occasionally I have one of my mac’s or other devices connected directly to the fiber network (A) for speed. But when I am connected to network A I can not print to the printer on B.
Is there a way to do this with your product?
Here’s a quick diagram to see if I’ve correctly understood the situation:
I’ve assigned arbitrary subnets to show the different networks.
It seems that you’ve got the Eero for wifi mesh features and it’s configured as a router as if it’s connected to the internet with NAT - the standard out of the box configuration. Unless you are actively using a lot of the Eero Plus features, the easiest solution is to put the Eero in bridge mode so that it simply passes through the subnet provided by the AT&T router. Then everything inside the house is on the same network.
But if you are actively using the Eero network services, the simplest solution would be to plug the Mac into one of the ethernet ports of the Eero base station. Now you will still be using double NAT as you go through the Eero and then again through the AT&T router which is not ideal, but you will be getting mostly wire speed as it will be a wired connection from end to end.
The other approach (if this is possible - not sure about the AT&T routers), if you can put the AT&T router in bridge mode and then setup the Eero as the primary router with responsibility for everything then you can plug your Mac into the back of the Eero and get full wire speed without the double NAT or even plug into the LAN ports of the AT&T router, which is inert in this configuration and would route through the Eero.
Zerotier won’t really help much in this situation unless you want to do some complex installations since you’ll need a router behind the Eero that the Mac will use for routing to the subnet where the printers live. A Raspberry Pi would do the job, but for occasional use even this seems like overkill.
Thanks for the diagrams!!
Hope they helped clarify things
