Port Already in Use Error with Dial-up VPN

If you are connecting to a Virtual Private Network through a modem and receive the Port already in use error when trying to connect, you might need to correct your connection settings.

To review/correct connections settings

  1. On the main menu, click Tools > Global Options.

  2. In the left pane, expand Connection, then clickDUN/LAN.

  3. In the right pane, click Connect to the Internet using a LAN. CuteFTP uses an existing connection defined on your computer.

  4. Click OK.

If Connect to the Internet using a LAN is already selected, verify your computer's VPN settings.

To verify your computer's connection settings

  1. Do one of the following:

    • In the Windows Control Panel, click Internet Options.

    • In Internet Explorer, click Tools > Internet Options.

  2. Click the Connections tab. The connection settings for one or more internet connections appear on this tab.

  3. The Dial-up and Virtual Private Network settings box displays dial-up and VPN connections that are defined on your computer.

  4. Click LAN Settings to view the local area network and proxy server settings.

IMPORTANT: Changing any of these settings can cause your computer to lose its connection to your network and/or the Internet. Do not change them unless you know what they should be. Your network administrator, Web hosting provider, or Internet Service Provider (ISP) can provide you with this information. Globalscape does not have this information; however, many ISPs provide this information on their websites.
