Guide to setup site to site transfer with flashFXP

[DanielPT]

Hey all.

I ahev spend a lot of time trying to get this work.

Im using flashfxp to transfer files from a Qnap nas to my own Qnao nas.
But im running into problems.

I have forwared port 50100 - 50200 in my router.
I have checked "use passiv ports" in qnap 50100-50200.

I have checked "FXP" on both sites. Checked "DOWNLOADER (NOT PASV)" and "Uploading (PASV)"

When i transfer 1 file it is owrking.
but when transfer alot of files like small .rar files i get this:

425 "Can’t open data connection":

When i try to transfer like 25 .rar files the first meaby 5-10 files transfer but then i get this error:

Transferred: 016.mp3 2,39 MB in 0,08 seconds (31,09 MB/s)

You may need to open more ports on your firewall as 100 may not be enough.

A new port is required for each transfer or directory listing I suspect that you're using all 100 ports before they're available for re-use again.

I would recommend increasing the port range from 100 ports to 300 ports and see if that helps.
