How to Unblock Port 43594 From My ISP


Ports enable you to establish a connection with other servers. Different programs, online services and applications use different ports to communicate with you. Your ISP may block certain ports for various reasons, including spam, malware or other threats that could affect the server. Port 43594 is used by peer-to-peer applications such as uTorrent and LimeWire, which are web services that enable you to share files with other people. If this port is being blocked by your ISP, you'll have to do several things to open the port.

  • Call your ISP and ask a customer representative to give your the port number they use for file sharing applications. When your ISP blocks port 43594, it will assign another port for peer-to-peer application. Jot down the port number for future reference.

  • Click "Start," "Control Panel" and then "Security" on the Control Panel menu of your computer.

  • Click "Windows Firewall." Choose "Allow a program through Windows Firewall."

  • Click "Add a port" on the firewall settings window.

  • Assign a name for the port number the customer service representative gave you. Choose something easy to remember, like "file sharing."

  • Enter the port number your ISP gave you in the "Port number" box.

  • Select the "TCP" check-box in the "Protocol" section. Click "OK." Repeat the aforementioned steps. This time, click the "UPD" check-box in the "Protocol" section "OK." This will enable this port in both TCP and UDP protocols. You can now use file sharing applications.
