CuteFTP v4 User’s GuideConnection – FirewallA firewall or proxy server is a safeguard utilized by many Local Area Networks (LANs) or Wide Area Networks (WANs) to protect the network from unauthorized access from the outside. If you are using CuteFTP with a firewall or proxy server, you may have some problems caused by the network settings. When you first try to use CuteFTP, leave these settings as they are and try to connect to some of the pre-defined sites in the Site Manager. If every site you try to connect to prompts you with “can’t connect”, or “can’t login, still trying”, then you probably need to configure the firewall settings. If your LAN or WAN supports FTP Proxy protocol, you will need the following information:1. IP address for your firewall host. 2. Port number for the FTP proxy server. 3. User name and password.Enter the three items above in the appropriate fields. Select the USER user@site radio button and the Enable Firewall Access box, then try connecting to a site. If you still have trouble, try again with the other options (OPEN Site, etc).The PASV Mode radio button specifies that CuteFTP will initiate all connections and the server will only wait for requests, therefore avoiding conflicts with the security system. NOTE: Only use this feature when experiencing problems with the default settings.Custom Proxy CommandsCustom firewall type is only necessary if the predefined firewall types do not work for you. To use custom firewall logons, select Custom and click the Settings button. Define a custom logon script in the box. The following variables may be used:%HOST% The address of the FTP site to connect. %USER% Valid username for the FTP server. %PASS% Password associated with the specified FTP username. %PORT% Port used by the FTP server. I f this command is not used, it will default to 21 (the standard FTP port). %FIRE_USER% Firewall username. Some network configurations may require a login for the firewall. %FIREPASS% Password associated with the firewall username.EXAMPLE OF CUSTOM COMMANDS:After setting the Host and Port fields to the correct firewall/proxy server, select the Custom option under Type, then click Settings. Enter each command necessary to initiate an FTP session with the remote server, one command per line. A typical series of commands might look like this:19
