Replying to Xbox and computer off of one ethernet port- how to piggy back xbox wireless from mac

pretty simple. 1st year residence, got hex box going, got internets going too.

but, with only one ethernet port, and two internet needing devices, idk what to do

if anyone knows of a way I can easily and efficiently piggy back my xbox wireless from my mac, that would be very nice

other than that, if there's a way to idk, split the ethernet port with some kind of splitter, that would be sick too.




basically, need two internets from one. go.
