I've been curious about this for a while now, as this is just a hobby thing rather than work thing but i love learning and trying new things so here goes: 1) is it possible to setup a mac mini as a IDS/IPF 2) is it advisable to do so or just get a old pc? 3) what software would be best (Icefloor? Little Snitch? etc?) 4) any other useful suggestions?
