How do I share my phone's internet but not through AP

[Android Central Question]

I have a WiFi router as an access point in a network. I would like my phone, when joined to the network, to be the default gateway. However, it seems the phone only allows it to share network via USB to a single device, or as an AP.

Any recommendations to share data with a network?

My ideas:
1) USB tethering with a computer on the network that is configured as the default gateway
2) USB OTG to ethernet adapter to WiFi router's internet port

Using the phone as the gateway is an interesting solution.
What is the problem you are trying to solve? Why do you want to do this?

To use a device as the gateway for a router, the device has to be connected to the router's WAN jack, not the LAN jack (and not via WiFi). In order to use a device connected via WiFi as the gateway, you'll need router firmware that can handle that - Tomato or DD-WRT may - may - be able to handle that. (Check on their forums.)

Hi- it's the OP. The reason for using a seapate AP is that some smart devices should be able to communicate each other even without the phone being around. Internet access is not required for these devices to work.

I ended up solving it with a Raspberry Pi 4 configured as a router with USB connection to my phone.

Yes, I understand it needed to be on the WAN jack, but my phone does not communicate over ethernet. It's USB.
