Windows 7 Windows 7 Blocking Port

Check for Other Security Software:​

• Third-Party Security Software: Apart from Avira Free Edition and Windows Defender, ensure there are no other third-party security applications that might be blocking the port.

Command Line Testing:​

• Command Prompt: Use the Command Prompt to check the status of the port. You can use the following command:
  Code:

   telnet localhost

  Replace with the actual port number you are trying to forward. If successful, you should see a blank screen indicating the port is open.

  Avira Free Edition Configuration:​

  • Avira Firewall Settings: Check the firewall settings in Avira Free Edition. There might be a setting in Avira that is blocking the port even though the Windows firewall is disabled. Ensure that the port is allowed in the Avira firewall settings.

    Disable Security Software:​

  • Temporary Disabling: Temporarily disable Avira Free Edition to see if it's causing the issue. Sometimes, even when the firewall is disabled, certain security software can still interfere with port forwarding.

    Windows 7 Networking Settings:​

  • Network Profile: Check if the network profile in Windows 7 is set to "Home," "Work," or "Public." Sometimes, being on a "Public" network profile can restrict certain network activities.

    Port Tester Tools:​

  • Multiple Tools: Try using different online port tester tools to verify if the port is open externally. Sometimes, one tool might not provide accurate results.
