Capture network traffic for wired C.E. devices

I often need to capture traffic for various consumer electronic devices to determine what API calls are being made along with the response.

This is quite easy to do with my MacBook and wifi capable devices. I simply connect the ethernet cable to my laptop and share my ethernet connection over my wifi. I connect the C.E. device through the shared wifi on my MacBook and capture all traffic on my computer with WireShark.

I need to do the same for devices that are not wifi capable and need to connect with ethernet. How can I route all wired device traffic through my computer so I can capture it with WireShark?

Thanks in advance for your help!
