Mad easy. Get Filezilla. Its freeware, and comes with a free server client. If your behind a router, open up port 21, and run it. Should work, thats what i do. I would suggest debian linux though. Works better. I run my apache server on there and it never crashes.
I second Filezilla it is awesome software. I had been using serv-u and then found Filezilla and never looked back.
P.S. dont forget about port forwarding on your router too!
