I often work on friends computers when they suspect a virus or some other malware and I'm wondering the best way to connect them to my network when I need to get out to the net. My home network is your simple cable modem into a Linksys router into a desktop. I want to connect this rogue machine to the router to get to the net, but I obviously don't want to risk infecting my own machine.
In the past, I've just simply powered off my own machine when it was time to connect the rogue machine, but this isn't always convenient.
My question is if I daisy chain two routers - in other words hang a separate router off my existing router and connect the rogue machine to that router - does that keep the two machines or maybe it would be appropriate to say two networks sufficiently sandboxed? Or is there even a better way?
