Windows Firewall Blocking Connections
Windows Firewall is Blocking Connections
Outgoing connections can be affected by the presence of firewall or antivirus software on the local computer or network connection. Windows comes with a built-in Internet Firewall that is active by default and blocks all FTP traffic. You can turn off this firewall (not recommended by Microsoft) or configure it to allow connections via CuteFTP. Configure your firewall so that ports 20 and 21 are open (not blocked). It may also be necessary to grant specific permission for CuteFTP to access those ports.
Follow the steps below to add CuteFTP to the Windows Firewall exceptions list.
To add CuteFTP to the Windows Firewall exceptions list
In the Windows Control Panel, double-click Security Center, then click Windows Firewall. On the General tab, ensure Windows Firewall is On and then clear the Don't allow exceptions check box. On the Exceptions tab, review the Programs and Services list to determine if CuteFTP is listed. Look for: CuteFTP (the interface)

The Add a Program dialog box appears. In the Programs list, click CuteFTP, then click OK. The Add a Program dialog box closes. Click Add Program. The Add a Program dialog box appears. Click Browse to navigate to the CuteFTP installation folder (by default in C:Program FilesGlobalscape), click then click Open. Click OK to close the Add a Program dialog box and save your changes.

Blocking Internet Access while Allowing Local Area Network (LAN) Access
You can configure Comodo Firewall to block Internet access while allowing free connections to an internal network (Intranet or LAN).
In your network at home, you want your child's computer to connect to other computers at home but disable Internet access to them for safety reasons
In your corporate network, you want your employee's computers to connect to your local network machines but disable Internet access for them for bandwidth restrictions
To selectively block connection to Internet whilst allow connection to internal network you need to create a Global Rule under Advanced Firewall Settings and password protect your configuration to prevent others from altering it.
To create a Global Rule
Open 'Tasks' interface by clicking the green curved arrow at top right of the 'Home' screen Open 'Firewall Tasks' by clicking 'Firewall Tasks' from the Tasks interface and click 'Open Advanced Settings'. Click 'Global Rules' under Firewall from the left hand side pane
Click the handle from the bottom and choose 'Add' from the options. The Firewall Rule interface will open.
Choose the following options from the drop-down menus:
Action = Block Protocol = IP Direction = Out
Enter a description for the new rule in the Description text box. Click the 'Source Address' tab, choose 'IPv4 Single Address' or 'IPv6 Single address' as per your network and enter the IP address of the computer in the IP text box. Click the 'Destination Address' tab, choose 'Network Zone' from the Type drop-down and choose your local area network from the 'Zone' drop-down.
Click the 'IP Details' tab and choose 'Any' from the 'IP Protocol' drop-down.
Click 'OK'. The created policy will be added to the list of Global Rules. Select the rule, click the handle from the bottom and click 'Move Up' repeatedly until the rule moves to the first position.
Click 'OK' for your configuration to take effect.
Your Firewall is now configured to allow access to internal network but to block Internet access. Now you need to password protect this configuration to prevent others from changing it.
To password protect your configuration
Open 'Tasks' interface by clicking the green curved arrow at top right of the 'Home' screen Open 'Advanced Tasks' by clicking ' Advanced Tasks' from the Tasks interface and click 'Open Advanced Settings'. Click 'User Interface' under General Settings from the left hand side pane Select 'Enable Password Protection' under 'Parental Control' and click 'Set Password' link.
