since ASG v7.x (I think it was since v7.400), I have a problem downloading more than approx. 3 files from ftp-Servers. I've attached a log-file of an ftp-session with NcFtpGet v3.2.3. (Download from ftp.serverX.de, 192.168.1.2 is my workstation's IP, and 195.1.2.3 is the external firewall-IP)
I can always download at least 1 file. But when NcFtpGet tries to download the 2nd or 3rd file, that doesn't work anymore. These files are pretty big, but I've also tried with small files on a public ftp-server (e.g. ftp://ftp.uni-paderborn.de/pub/doc/AG/KB/csl/) It's the same problem.
I also noticed that when I download a small file from ftp://ftp.uni-paderborn.de/pub/doc/AG/KB/csl/ then wait for 30 seconds, I can't download anything anymore. I can't even download the same file once more. These are the Total Commander log-file-entries when I download the first file from ftp.uni-paderborn.de:
PASV
227 Entering Passive Mode (131,234,16,25,171,156)
RETR grants.ps
150 Opening BINARY mode data connection for grants.ps (69537 bytes).
Herunterladen: 26.868 Bytes
Warte auf Antwort des Servers...
226 File send OK.
Copied (28.10.2009 17:19:22): ftp://ftp.uni-paderborn.de/pub/doc/AG/KB/csl/grants.ps -> D:\ftp-test\grants.ps 69.537 Bytes, 180.7 kbytes/s
Then, 8 seconds later, I tried downloading another file:
PASV
227 Entering Passive Mode (131,234,16,25,150,90)
RETR hotel.ps
150 Opening BINARY mode data connection for hotel.ps (64966 bytes).

PASV
227 Entering Passive Mode (131,234,16,25,70,47)
Then I get an "error while downloading"-message.
I also tried to download those 25-MByte-files from ftp.serverX.de with Total Commander 7.04a and I get the same error message as with NcFtpGet:
500 I won't open a connection to 192.168.1.2 (only to 195.1.2.3)
What's wrong? Can somebody help me?
