FTP Problem (external)
|
|
|
| Windows SBS 2003 Sever running ISA 2000 sp2 and IIS 6.
Have set up the FTP server as per microsoft knowledge
base, also double checked against acticle on isaserver.org.
Anyway, when accessing the FTP site via IE6 (fully updated
and ftp folder view enabled) I get the following error.
FTP Folder Error
X An error occured opening that folder on the FTP
Server. Make sure you have permission to access that
folder.
Details:
200 Type set to A.
500 Invalid PORT Command.
500 'LPRT 6,16,0,0,0,0,0,0,0,0,67,0,0,0,0,0,133,96
,2,66':
command not understood
I get the following error when accesing via ftp.exe
(command prompt)
ftp> ls
500 Invalid PORT Command.
150 Opening ASCII mode data connection for file list.
Aborting any active data connections...
425 Can't open data connection.
Also when using Ws_FTP file begin trasfer than error out.
Files actually show in ftp directory on server but size is
0k.
I am loging in with admin account, all users of domain
have full access(ntfs permission on ftp directory). Along
with the iuser. Plus defaults. Anyone have any ideas
here?????
Also, FTP site works perfectly internally.

| This is related to passive mode.
is it NAT'ed ? by ISA or ???
and verify this

_Security.html
(I know you did, just pay attention on the passive mode section)
and read this too.

| The reason for ftp.exe not working could be caused by ftp not binding to
port 21.
and NAT device not working correct with that port, and I'm also guessing
that passive mode doesn't work.
