I've been trying to find a step by step to this with google but no luck. Maybe someone can point me to one or help me out here. Basically we have a Static IP from our ISP and we want to be to access the files on a single mac here from anywhere. We have a router so I'm not sure how that inteferes with anything. I know if I hooked up straight to the Cable Modem this is a sinch. But what do I need to do when I'm behind a router? In addition for future refrence can i have multiple machines do this from the same IP address? The file serving machine is a Dual 2 ghz G5 with 4 Gigs of ram 1.5 Terabytes of Hard Drive space. Running 10.4.9. This would all be mac to mac sharing. Thanks. If i left out any info that could help you answer my question let me know!
