Well, initially I tried to use hfs. I had used it before and it seemed extremely simple and easy. In cases where I had to send somebody a file that was too large to send via email I would put it in a folder and serve it via hfs. The receiver just had to type my IP address in their browser and they could get the file. It lets you set up login password and set a folder for downloads. But, now my computer is in a network where it gets its IP from the D-Link router. For some reason, the computer outside my network, when the receiver types in the IP address, can't connect to my server. I installed Filezilla server. It seemed to go alright, but the same thing happens when my receiver tries to log in with the Filezilla client. I think I have to set something in the router to allow an external computer to reach into one of the computers inside my network. I don't know. Does that sound right?
