mkrall -> FTP Publishing (2.Jul.2008 10:21:11 AM)
|
I am using ISA2006 publishing an FTP server on Win2003 IIS. At one time it was working. I am sure I modified the configuration somewhat since it worked, but did not change anything related to that particular published server. FTP still works from inside the network, but not from the outside through ISA.
I have tried two different FTP clients as well as a dos prompt. When I log in from DOS I am able to connect and log in, but when I issue a "dir" command, I get a "connection closed by remote host" message. The FTP clients give error messages along the lines of "error retrieving directory listing". I have tried both passive and active mode on the FTP clients, I have tried both settings in ISA for whether the requests appear from ISA or the client, I have tried pointing the default gateway of the IIS box at both the inside router(this was the setting in use when everything worked) as well as the internal NIC of the ISA box. I even went so far as to back up the configuration and run the edge firewall wizard to reset the entire configuration and then add in the one rule for FTP publishing.
I am not sure what else to try, does anyone have any ideas?
