Yes, it does work with power-over-ethernet adapters. I own quite a few adapters like this. What happens is it creates a data connection for USB Ethernet using 2 USB pins and uses the other 2 USB pins for power. It seems strange to think of it like this, but these devices split power and Ethernet into 2 pieces. If your device is compatible (which Raspberry Pi ...

If you want to PoE (Power over Ethernet) the Raspberry Pi, you'll need a PoE Hat to power the the Raspberry. However you'll need to ensure the other end of the ethernet cable is connected to a PoE port too (ie PoE switch).

Ethernet shields are neither input or output, they are both. Generally they are used as a transceiver where data is sent and received by the same shield over the same cable. If you can open a web page with it, it is working just fine both sending and receiving. I believe your best solution is to purchase a small ethernet switch, they are only a few shekels ...

Yes, it is possible to have either a router or a bridge between your local network and the internet router. With a router you will have two subnets with different ip address ranges, each interface connected to one subnet. So you have to manage some simple routing configuration to your subnets, at least a static route on your internet router. Or you use ...

I can not change the MAC address of eth1 because it is on the USB ethernet adapter, right? The MAC address will always change and the USB adapter is loaded after the network card on the ...
