Raspberry Pi - Bridge WLAN to local LAN
Object: Use a Raspberry Pi (RPi) to connect to a WiFi network (offering internet access) and “bridge” that using the ethernet port of the RPi to the WAN port of a WiFi router to act as a gateway for local endpoint devices. It is also possible to “bridge” the RPi ethernet port directly to a switch where other devices can get network access using an ethernet cable (or a single computer directly connected to the ethernet port of the RPi). “Schematics” for communication/setup: Internet > WiFi access point > WLAN NIC on RPi > Ethernet NIC on RPi > WAN port of a WiFi router > local WLAN (or ethernet ports) of the WiFi router > local endpoint devices/clients or, for a switch: Internet > WiFi access point > WLAN NIC on RPi > Ethernet NIC on RPi > switch port > local endpoint devices/clients via ethernet cable Things needed: Raspberry Pi (either an older one without onboard WLAN NIC or one with an onboard WLAN NIC) Raspberry Pi OS Lite, lates
