I have a large set of files I need to have transferred to me (about 7GB) and I need them before I leave for the holidays, so posting a high-density DVD won't work. I would like to set up my computer as a temporary FTP that my colleague could transfer the data to. I've set everything up according to most of the help files I can find online. It's pretty straightforward, but my colleague still cannot connect to my machine. I'm running a MacBook Pro with Snow Leopard. FTP sharing is on. I've set up port forwarding for port 21 (I am connecting wirelessly through a router). Firewall is open for FTP sharing. I've set up a user account for my colleague. Still, he can't access it. He is, however, only using the Connect to Server option under the Go menu in Finder. Not sure what the issue is here. I've even set up a DynDNS domain and have the DynDNS updater. I'm at the limits of my technical know-how here, and any help or advice would be appreciated.
