Windows 10: How to block an IPv6 address in windows firewall

I have noticed some suspicious activity on my computer. My Gmail password might even have been changed I’ve not change the back, so I am very concerned.


The activity seems to be coming from an iPv6 address. So, I would like to block it with windows firewall.


Unfortunately, I am not at all familiar with IPv6. From the little I’ve learned, I think the beginning part of the address identifies the network/router and the end of the address identifies the specific computer. Apparently, that can hide the actual unique address MAC of the computer for privacy reasons.


So, if I’m right about that and I have no idea if I am, I assume I need to block a range of addresses.


I don’t know how to block any IPv6 address, or a range of IPv6 addresses.


Can anyone help me?

I am using a Microsoft surface pro 4 which may not matter running Windows 10 Pro

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.

 

Windows firewall blocks ipv6

I use the newest windows 10 and have both ipv4 and ipv6 addresses on my pc. When I make a outbound rule for blocking some ipv4 addresses, I can't visit any ipv6 websites. The browser says "Your Internet access is blocked". When I delete the rule, everything
is ok. I think a recent windows update make this, because a week ago there was no problem.

 

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.
