Good catch on the coaster, don't tell my wife.
Right side of the table, PC/monitor at the bottom is my company laptop; PC/monitor at the top is for accessing our customer's network so I can continue to support them. After VPN, I RDP to their lab network.
Left side of the table, switch is connected to the LAN side of the Residential Gateway in our house, and then the 2 block boxes at the bottom are plugged into the switch so I have 2 "lab" RG's at the house for testing. The 2 laptops are for testing and plugged into the 2 black boxes at the bottom.
The pic is missing 2 Raspberry Pi's that have since been added.
