FTP service and Windows Firewall on Server 2003

[Guest Viktor Jevdokimov]

Hi all,

 

Environment:

- Windws Server 2003 R2 Standard Edition Service Pack 2

- IIS with FTP service

- Windows Firewall enabled, TCP ports 21 and 20 are enabled both on

exceptions list and on connection.

 

Problem: "Connection closed by remote host." right after user name is

entered when connecting from outside.

 

When testing locally on the server or when Windows Firewall is disabled -

everything is fine, no problems. When Firewall is enabled, connection from

outside just drops right after user name is entered.

 

IIS log file shows 421 FTP status and 121 win32 status.

 

How to configure Windows Firewall properly for FTP service to work from

outside?

 

Thanks in advance,

Viktor

You may have to run the ftp client in pasv mode:

Passive mode or active - no difference, since connection is closed before

asking for a password.

Problem solved:

 

1. Uncheck "FTP Server" in Windows Firewall Extended tab for every location

2. Add 21 port to exceptions
