In my house, i'm running a server I use for testing purposes, and I'm planning on throwing away my knackered router, and making the server my Gateway to the internet and using it as a server for several other applications (mostly on IIS), as well as desktop interaction with my desktop pc.
Now the server is running Windows Server 2008, and im not sure if maybe using an old computer (still fast) as a Linux Gateway instead, and have it point specific ports to the server. Don't really know about security, and I was wondering either how Linux could be more secure or Windows could be more secure.
