Windows 10: I have a basic windows firewall configuration question. I want to block all outgoing ip...

Folks, I have a windows firewall configuration question. I want to. block all outgoing connections to a specific port for all ips/interfaces. but then allow one specific external ip range to be reachable on that port. I tried setting a block all outgoing firewall rule ,and then created an allow one ip to be reachable. This did not work. I am reading that windows firewall prefers block over allow, per documentation. How are other achieving this on windows?

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.

Can Windows Firewall block outgoing connections yet? If not, it's one step above useless.

Look into Online Armor for a free firewall.

 

Windows Firewall blocking websites

I have blocked IP addresses, e.g. 255.255.255.255, not URLs, e.g. somewebsite.co m.

As far as unblocking, look at your Windows Firewall rules. Do you see anything that is blocked? If you do, click on the Scope tab and see what is listed there.
