    • The Windows Defender Firewall can block network traffic for IP (Internet Protocol) addresses. However, some users might need to unblock a range of IP addresses on their home networks. Users can do that by setting up a rule that permits an IP address range through the Windows Defender Firewall. This is how users can set up a firewall rule that permits an IP range.
