Default Port Settings on a 1&1 Server Windows

Learn how to do an initial setup of port settings for your 1&1 Dedicated Server Windows.

For security reasons, almost all the ports in Windows Server 2003 are closed initially (or after a re-image of your Windows Server). Before you can use the server for FTP, you must open the default ports as outlined below.

Please note:
If your server is running Windows Server 2008, these common ports will already be open. It is suggested to check the "IP Security Policies on Local Computer" and allow/block access as necessary for your setup.
