Using FTP programs with ZoneAlarm Pro

To use FTP (File Transfer Protocol) programs, you may need to make the following settings adjustments in your FTP client program and in ZoneAlarm Pro.

• Enable passive or PASV mode in your FTP client

  This tells the client to use the same port for communication both directions. If PASV is not enabled, ZoneAlarm Pro may block the FTP server's attempt to contact a new port for data transfer.

• Add the FTP sites you use to the Trusted Zone
• Give Trusted Zone access permission to your FTP client program.

To learn how to add to the Trusted Zone and give access permission to a program, see Related Topics.

access permission
Access permission allows a program on your computer to initiate communications with another computer. This is distinct from server permission, which allows a program to "listen" for connection requests from other computers. You can give a program access permission for the Trusted Zone, the Internet Zone, or both.

Several common applications may need access permission to operate normally. For example, your browser needs access permission in order to contact your ISP's servers. Your e-mail client (for example, MS Outlook) needs access permission in order to send or receive e-mail.

The following basic options are available for each program:

Allow the program to connect to computers in the Internet Zone / Trusted Zone

Block the program from accessing computers in the Internet Zone / Trusted Zone

Ask whether the program should have access permission (show Repeat Program alert)
