DISCUSSION
FTP connections can be affected by the presence of firewall or antivirus software on the local computer or network connection. Either one can block the ports needed to make a successful FTP connection to the remote server.
If you are using a personal firewall software package, configure it so that CuteFTP will be allowed access to the Internet on ports 20 and 21. It may also be necessary to grant specific permission for CuteFTP to access those ports. If so, then you may need to add cuteftp.exe (or cuteftppro.exe) and ftpte.exe to an exception list.
If you need help configuring your personal firewall software please consult the firewall program's help file or the technical support area of the manufacturer's Web site.
For more information about firewall configuration and some helpful links to manufacturer Web sites, please refer to GlobalSCAPE Knowledgebase article #10133
