firewall rule to block addresses NOT on an IP list?


I am just starting to learn the Windows Firewall (working on both Windows 7 and 10) and I'm not impressed with the inflexibility of its rules. I would like to know if


1. Is there is a way to do what I want with Windows Firewall?
2. Is there is a third-party firewall that would do it?


What I want to do is create a rule that blocks outgoing connections, for program X, that are to a destination **NOT** in an IP list.


Windows Firewall is not very flexible in how you specify IP list rules. When you give an IP list, your rule will match that list... you can't say "trigger the rule for non-matching IP addresses." Therefore to allow outgoing connections to a list, you have to


1. Change the entire firewall policy to block outgoing connections by default so that you can create an "allow rule" matching your list. This will mess up the rest of your programs.


2. Somehow combine a block rule and allow rule. Create a block rule for most traffic, with the "allow" rule overriding it when appropriate. However, this doesn't appear to be possible in general. It **may** be possible for connections that use IPSec, I'm not sure. And I'm not sure if I can use IPSec in my application.

And is there a third-party firewall that can do it? Most 3rd-party firewalls are LESS sophisticated than Windows Firewall, because the use case they are addressing is providing an interface that doesn't require much comprehension. I need one that's actually MORE sophisticated than Windows Firewall.

 

Firewall Rules

Can you setup exceptions for firewall rules? For example, if I have a port blocked inbound for ALL via GPO, can I create an exception to that rule to allow just certain IP addresses to get through the port being blocked? Win 10 ENT in a domain environment.

 

Hello, I've created firewall rules to block several remote ip addresses for inbound connections and Windows firewall 11 is ignoring my custom firewall rules

Hello,

Based on the information you provided, it seems like you have already created custom firewall rules to block several remote IP addresses for inbound connections, but they are not working as expected. You also mentioned that you are still receiving unwanted emails from these IP addresses.

I found a thread on the Microsoft Community forum that discusses a similar issue. One user suggested that you should check if the Windows Firewall service is running and set to start automatically. You can do this by following these steps:

1. Press the Windows key + R to open the Run dialog box.
   
2. Type “services.msc” and press Enter.
   
3. Scroll down to find the “Windows Firewall” service.
   
4. Check if the service is running and set to start automatically. If not, right-click on the service and select “Properties”. Change the “Startup type” to “Automatic” and click “OK”.
   

If the service is already running and set to start automatically, you can try resetting the Windows Firewall settings to their default values. Here’s how:

1. Press the Windows key + R to open the Run dialog box.
   
2. Type “cmd” and press Ctrl + Shift + Enter to open an elevated Command Prompt.
   
3. Type the following command and press Enter: netsh advfirewall reset
   
4. Restart your computer.
   

Please note that resetting the Windows Firewall settings will remove all custom rules that you have created. You will need to recreate them after resetting the settings.

I hope this helps! Let me know if you have any other questions.
