I’d like to use resinOS 2.x to route traffic between a WiFi network and an Ethernet device, such as an actual router, plugged into the Ethernet port on my Raspberry Pi 3. With resinOS 1.x a solution was created here:
Since newer versions of resinOS are using Network Manager the above approach may no longer work.
The BridgeNetworkConnectionsProxyARP doc on the Debian Wiki seems to have a solution. But it’s not clear how it would be applied under resinOS 2.x.
How can I route WiFi traffic to Ethernet with resinOS 2.x using Network Manager?
