@bot @olmitch @meso NAT is the magic behind why you can have a ton of devices on a single public IP address leased from your ISP. It keeps track of the connections your devices make so that when the reply comes back, it knows which device to send it to. This is all on the IP layer and has nothing to do with MAC addresses, which just help the switching part of your router find the device on the LAN. Switching and routing are two entirely different things, for the record.
