My home network is weird, and it’s taken me, ... uh... way too much work to get it set up how I want it. I’ve decided to post the bulk of my current router configuration as a help to other people who are similarly weird.
The other day I was sitting at home when I realized that my network switch was going crazy. The switch in question is a gigabit switch that is connected to my home server (which is my home’s gateway device — the one connected to the modem), to a wireless router, and to a desktop machine that acts as a media box (it’s connected to a TV and stereo system). By “going crazy” I mean that all the lights were flashing as fast as they could. There is a light for each connected device, and when it flashes it means that that device is either sending or receiving data — meaning that in this case packets were going to or from my server, my media box, and my wireless router (which by proxy means my laptop, my phone, my wife’s phone, etc) apparently about as fast as possible. Recently there have been some high profile DDOS attacks by botnets of unprecidented size. “Am I part of a botnet?”, I wondered. “Did I make some serious security mistake, despite generally being much more careful than average about security?”.
