I'm trying to buy (from ebay) a cisco switch, router and pix firewall for learning purposes. All these will be connected to a Linksys ADSL modem which also has wireless capability. The OSs will be OpenBSD4.1, Windows XP and Linux distros. I will probably also try IPv6 (not sure if that has got anything to do with this). I had a look at cisco catalyst 1900 series switch and it looked ok.
Could anyone recommend anything that would be great for leaning purposes and also be able to handle daily Internet traffic? Thanks.
