Windows 8 Windows Firewall Cant Close Open Ports

[Aubrey Bourke]

Hi,

I am new to using windows firewall and am very keen on it. However I have a few questions that I cant figure out.

1. I have set block incoming rules for a few nvidia executables. However in resource manager it says that these executables are running allowed. They are the last four executables on the screenshot of open ports in resource manager. So can someone tell me exactly how do I close those ports (disallow)?

2. In resource manager there are three graphs that show networking information. a) Network b) TCP connections and c) Ethernet
I am glad that my Ethernet connection is not transmitting very much. But Im not too sure what the other two graphs are for. Guessing perhaps the TCP connections is internal to the loopback interface? I see mostly nvidia and f-secure doing this. Does that mean they are connecting to a proxy server internally? The network graph is a mind melter and cant work out what information its presenting. Can anyone clarify this for me?

Kind Regards
Aubrey

Hello Aubrey, I can help clarify the questions you have regarding the Windows Firewall and the Resource Manager. 1. Blocking Nvidia Executables with Windows Firewall: To effectively block the inbound connections associated with the Nvidia executables using the Windows Firewall, follow these steps: - Open Windows Defender Firewall settings. - Navigate to "Advanced settings" on the left-hand side. - Click on "Inbound Rules" in the left pane. - Look for the rules associated with Nvidia executables and ensure they are set to "Block" rather than "Allow." If the rules are set to "Allow," you can edit them to change the action to "Block." 2. Understanding Resource Manager Networking Graphs: - a) Network Graph: This graph shows overall network activity, including all processes that are using the network bandwidth. It gives you an overview of the total network usage on your system. - b) TCP Connections Graph: This graph displays the active TCP connections on your system. TCP (Transmission Control Protocol) is a connection-oriented protocol used for data transmission, and this graph shows the connections established using TCP. - c) Ethernet: This graph represents the network utilization specifically for your Ethernet connection, showing how much of your network bandwidth the Ethernet connection is using. Regarding the TCP connections involving Nvidia and F-Secure, it could indicate various activities such as updates, telemetry, or other communications with servers. It doesn't necessarily mean they are connecting to a proxy server internally. The network graph typically aggregates all network activity, including both TCP and UDP traffic, providing an overall view of network usage. If you have further questions or need more detailed guidance on specific settings, feel free to ask!
