Hi Métek,

Turn off packet filtering and you'll be able to use PASV.

Hi Métek,

You can to use PASV FTP client AT the ISA Server itself? From the ISA
Server console?

Thanks!

Tom

Hi Métek,

Not sure what the problem is, since log that I show here demonstrates
that PASV works fine to ftp.coba.net

PORT mode is working well.  I don't have access control blocking FTP..
To
be able to download files from their server, we need to be in passive
mode.
There's the problem !!  Because in active mode, like I just said before,
there's no problem...

Do you have access controls blocking FTP access? Have you tried PORT
mode? 

HTH,
Tom

troubleshoot this issue.

I'm looking at this problem for 2 days now..... Help me please :D

Using: WS_FTP95 LE

When an internal client (SecureNAT) behind the isa server is connecting
to
a FTP site, there's no problem at all if it's in active mode.

In passive mode, can connect without problem, upload without problem,
change directory without problem.....  but cannot download any files...
check this exemple (trying to download):

227 Entering Passive Mode (XXX,XXX,XXX,XXX,4,44)
connecting to XXX.XXX.XXX.XXX:1068
- -
connecting to XXX.XXX.XXX.XXX ...
Connected to XXX.XXX.XXX.XXX port 1068
LIST 
150 Opening ASCII mode data connection for /bin/ls.
Received 1078 bytes in 0.1 secs, (100.00 Kbps), transfer succeeded
226 Transfer complete.
CWD colwin50
250 Directory changed to /e:/pub/clients/250506/colwin50
PWD
257 "/e:/pub/clients/250506/colwin50" is current directory.
PASV
227 Entering Passive Mode (XXX,XXX,XXX,XXX,4,66)
connecting to XXX.XXX.XXX.XXX:1090
- -
connecting to XXX.XXX.XXX.XXX ...
Connected to XXX.XXX.XXX.XXX port 1090
LIST 
150 Opening ASCII mode data connection for /bin/ls.
Received 521 bytes in 0.1 secs, (50.00 Kbps), transfer succeeded
226 Transfer complete.
receiving colcla32.zip as colcla32.zip (1 of 1)
TYPE I
200 Type set to I.
PASV
227 Entering Passive Mode (XXX,XXX,XXX,XXX,4,71)
connecting to XXX.XXX.XXX.XXX:1095
- -
connecting to XXX.XXX.XXX.XXX ...
Connected to XXX.XXX.XXX.XXX port 1095
RETR colcla32.zip
150 Opening BINARY mode data connection for colcla32.zip (2339925
bytes).

And it freezes there.......

On my ISA Server 2000 SP1, in protocol rules, I set a rule with the FTP
DOWNLOAD ONLY protocol (application filter).  I tried the FTP protocol
(application filter).  I did a lot of test...  When passing from the
other
side of the ISA, it works perfectly..
