FlashFXP uploading files drectly from another FTP


I’m trying to use FlashFXP to transfer my files directly from my previous hoster. I successfully connect to both FTPs simultaneously, but when i’m trying to transfer files FlashFXP writes:

[L] 227 Entering Passive Mode (66,172,94,30,190,196)
[R] PORT 66,172,94,30,190,196
[R] 200 PORT command successful.
[R] STOR aab468x60.gi

and does nothing.

Have you tried this ? Does DreamHost support FTP to FTP transfer ?
