1.  What is the purpose of "Linux box"?

2.  What is the make and model of "my router"?  What is its purpose? 
What port is the "Linux box" connected to?  What port is the "Win2K box" 
connected to?

3.  What is the purpose of "Win2K box"?

4.  Are there any other devices or hosts, such as a Wi-Fi access point, 
Wi-Fi interface in "my router", pods, phones, tablets, game consoles, 
laptops, etc.?
