This is definitely not problem on the client side. Filezilla has some method how to recover from this server problem, our client does not. In previous case (
http://forum.altap.cz/viewtopic.php?f=7&t=3491) server incorrectly sends its private IP address (inaccessible from FTP client placed outside of private network with the server) instead of expected public IP address. Do you think it is the same problem here? Can you send at least first two numbers from PASV reply? (I expect "
227 Entering Passive Mode (192,168,..."). And please send also first two numbers from server's IP address. Thanks!

Thanks! IP address range 172.16.0.0 – 172.31.255.255 is reserved as private address space, so it confirms that the problem is the same as
http://forum.altap.cz/viewtopic.php?f=7&t=3491. OK, I'll try to bypass this server problem, couple of years it was unknown for us, now it is tending to be frequent.
One more question, what are the first two numbers from the server IP address? (Try "ping server-name" or read it from FTP log.)

It works on 21 but doesn't on 10156.
I can only guess that the router between the client and the server is smart enough to translate addresses in FTP :21 traffic, but not with other ports. Or something else, I'm not sure.

It could as well be that the server got screwed up.

Excellent.
Anyway, I think it'll be interesting to see the logs (with the IPs) after changing the listening port on the server back to 21.

OK, thanks. It's not in private IP address range (as expected).

Are there any updates to the ftp plugin yet?

BUMP
Not sure if this is related, but I just installed Beta#2 and tried the FTP plugin on GoDaddy.com. I was able to connect and it just hung waiting to download directory listing.

Sorry, no updates, try to change transfer mode (passive (PASV)/active(PORT)).

Bummer. I could not even use this on GoDaddy.com and had to resort to FireFTP
