I am a college student without a lot of money so I am turning one of my Raspberry Pis into a router.
I followed these instructions in general to create a Raspberry Pi that plugs directly into my modem and creates a WiFi network.
Some other things I did were to install Fail2Ban and other basic security things when I first launched the Pi.
I have some devices that will need to connect by Ethernet. I have a USB to Ethernet adapter and a Ethernet Switch. I was hoping to have the internet sent through the USB to Ethernet adapter (ETH 0) to my Switch, that can plug into devices that need a wired connection.
I need the internet that goes out of the eth1 device and out of the wlan0 device to be on the same subnet. How do I set this up where they are both on the same subnet?
