FDT is an Application for Efficient Data Transfers which is capable of reading and writing at disk speed over wide area networks (with standard TCP). It is written in Java, runs an all major platforms and it is easy to use. FDT is based on an asynchronous, flexible multithreaded system and is using the capabilities of the Java NIO libraries.
I have a home Raspberry Pi, which I use as a NAS. The brilliantly-designed FDT is supercharged for transferring large files. Occasionally, I need to access those files when I am outside, using my Macintosh. I set up port forwarding for the ports 54321 and 43210 since I've noticed FDT uses them. However, the FDT server starts and stops with errors on my Raspberry Pi.

What ports should I set up for port forwarding? Should I enable mapping? Should I allow both the TCP and UDP protocols? I would appreciate any help.
