Need some advice over a LAN Configuration
I need some advice about an idea: I want to split a LAN in two parts using my current hardware configuration.
Let's explain ...
I have 2 wired PCs and and an wireless AP connected to a simple switch. The whole LAN is managed by a Linux Firewall/Gateway (currently running Ubuntu TLS ... but i'll switch to gentoo soon) that's connected to my dsl modem.
Now from some time I live with other people that connects to me to do some simple tasks over the internet like chat, writing emails ... (other stupid things). All went good until they found p2p ...
I was thinking about split my LAN by 2 making my own private and another for the others. After some thinking my train of thought shored over interface Multicast and the omnipresent IPtables ... but can't get a clue on how to put alltogether so that my lan master could automatically identify my machines and put that in the right LAN (obviously through the MAC address) (:
I'm just experimenting so any advice/idea is welcome ;)
