Windows 7 Windows 7 Blocking Port

[sailoholic]

I have spent the last two hours trying to open a port for a remote control application.

I have tomato 1.27 running on an asus wl500gP router.

I am running windows 7 ultimate

i have an Arris voip modem through comcast

The problem is this, i forwarded the port correctly in tomato yet the port is still closed. I have tried the following:

Enabling DMZ
Disabling windows firewall by either the control panel or through services.msc
Enabled UPNP in the application, it opens the port according to tomato yet external port testers still say its closed
reset the router and pc numerous times
hard reset the router
Hooking PC directly into cable modem

I believe that this is strictly a windows 7 issue now as the router is out of the equation. The only security software I have is Avira free edition, windows defender, and (disabled) windows firewall.

Can anyone give me help as to why I cannot open a port? It would be greatly appreciated as I am leaving for a trip in 36 hours and would like to be able to remotely control this application.

It sounds like you've taken thorough steps to troubleshoot the issue with port forwarding on your Windows 7 Ultimate system. Since you've eliminated the router as the source of the problem, the issue likely lies within the Windows 7 system. Here are a few more steps you can take to troubleshoot and potentially resolve the port forwarding issue on your Windows 7 system:

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:

   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.

If these steps don't resolve the issue, consider seeking assistance from Avira's support or checking Windows 7 community forums for similar issues and solutions. Remember, the security software configurations or network settings might be the key to resolving the port forwarding problem on your Windows 7 system.
