Set the permissions to allow anonymous access: Open a command prompt. Type the following command: ICACLS . You are not required to use this path; however, if you change the location for your site you will have to change the site- related paths that are used throughout this walkthrough. Once you have configured your firewall settings for the FTP service, you must configure your firewall software or hardware to allow connections through the firewall to your FTP server. If you are using the built- in Windows Firewall, see the (Optional) Step 3: Configure Windows Firewall Settings section of this walkthrough. If you are using a different firewall, please consult the documentation that was provided with your firewall software or hardware. Use the FTP Site Wizard to Create an FTP Site With Anonymous Authentication. In this section you, create a new FTP site that can be opened for Read- only access by anonymous users. Whereas Chapter 1, First steps gave you a quick introduction to VirtualBox and how to get your first virtual machine running, the following chapter describes in.

You configured the external IPv. FTP site.(Optional) Step 3: Configure Windows Firewall Settings. Windows Server 2. If you choose to use the built- in Windows Firewall, you will need to configure your settings so that FTP traffic can pass through the firewall. There are a few different configurations to consider when using the FTP service with the Windows Firewall - whether you will use active or passive FTP connections, and whether you will use unencrypted FTP or use FTP over SSL (FTPS). Each of these configurations are described below. Note. You will need to make sure that you follow the steps in this section walkthrough while logged in as an administrator. This can be accomplished by one of the following methods: Logging in to your server using the actual account named . For more information about UAC, please see the following documentation: Note. While Windows Firewall can be configured using the Windows Firewall applet in the Windows Control Panel, that utility does not have the required features to enable all of the features for FTP. The Windows Firewall with Advanced Security utility that is located under Administrative Tools in the Windows Control Panel has all of the required features to enable the FTP features, but in the interests of simplicity this walkthrough will describe how to use the command- line Netsh. Windows Firewall. Using Windows Firewall with non- secure FTP traffic. To configure Windows Firewall to allow non- secure FTP traffic, use the following steps: Open a command prompt: click Start, then All Programs, then Accessories, then Command Prompt. To open port 2. 1 on the firewall, type the following syntax then hit enter: netsh advfirewall firewall add rule name=. In addition, the FTP client machine would need to have its own firewall exceptions setup for inbound traffic. FTP over SSL (FTPS) will not be covered by these rules; the SSL negotiation will most likely fail because the Windows Firewall filter for stateful FTP inspection will not be able to parse encrypted data. AUTH SSL or AUTH TLS commands, and return an error to prevent SSL negotiation from starting.)Using Windows Firewall with secure FTP over SSL (FTPS) traffic. The stateful FTP packet inspection in Windows Firewall will most likely prevent SSL from working because Windows Firewall filter for stateful FTP inspection will not be able to parse the encrypted traffic that would establish the data connection. Because of this behavior, you will need to configure your Windows Firewall settings for FTP differently if you intend to use FTP over SSL (FTPS). The easiest way to configure Windows Firewall to allow FTPS traffic is to list the FTP service on the inbound exception list. The full service name is the . Each FTP client requires two connections to be maintained between client and server: FTP commands are transferred over a primary connection called the Control Channel, which is typically the well- known FTP port 2. FTP data transfers, such as directory listings or file upload/download, require a secondary connection called Data Channel. Opening port 2. 1 in a firewall is an easy task, but this means that an FTP client will only be able to send commands, not transfer data. This means that the client will be able to use the Control Channel to successfully authenticate and create or delete directories, but the client will not be able to see directory listings or be able to upload/download files. This is because data connections for FTP server are not allowed to pass through the firewall until the Data Channel has been allowed through the firewall. Note. This may appear confusing to an FTP client, because the client will seem to be able to successfully log in to the server, but the connection may appear to timeout or stop responding when attempting to retrieve a directory listing from the server. The challenges of working with FTP and firewalls doesn't end with the requirement of a secondary data connection; to complicate things even more, there are actually two different ways on how to establish data connection: Active Data Connections: In an active data connection, an FTP client sets up a port for data channel listening and the server initiates a connection to the port; this is typically from the server's port 2. Active data connections used to be the default way of connecting to FTP server; however, active data connections are no longer recommended because they do not work well in Internet scenarios. Passive Data Connections: In a passive data connection, an FTP server sets up a port for data channel listening and the client initiates a connection to the port. Passive connections work much better in Internet scenarios and recommended by RFC 1. Firewall- Friendly FTP). Note. Some FTP clients require explicit action to enable passive connections, and some clients don't even support passive connections. These firewall filters are able to detect what ports are going to be used for data transfers and temporarily open them on firewall so that clients can open data connections. Many firewalls now employ these features, including the built- in Windows Firewall.
