We have set an FTP server twice now, when not running it over SSL we can connect and work without an issue.<br />
<br />
The issue we are having is:<br />
<br />
When we switch it over to use the SSL certificate we can connect, it then gives an error 425 when trying to LIST the contents of the FTP directory. Shortly after this error we are left unable to connect and the FTP client states that a larger than expected TLS packet was received (this is in FileZilla and other FTP clients don’t show this error, it is apparently some built in FileZilla feature to spit out this error and not connect when it detects something wrong with the connection – after a certain amount of time you can connect again, get the list error and back around in circles).<br />
<br />
We have opened up all the necessary ports on the Firewall (21, 22, 989, 990) custom ports also, however, it just stops in its tracks.<br />
<br />
The server is running IIS 7 with FTP component 7.5<br />
<br />
We also tried using CoreFTP server application to host the FTP site instead of Windows Server doing it and received the same error message again.<br />
<br />
Any help would be much appreciated.

FTPS dropping connection with error 425

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.

Microsoft IIS Web Server

Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. SSH was designed as a replacement for Telnet and for unsecured remote shell protocols. The term telnet is also used to refer to the software that implements the client part of the protocol. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server.
