How to Block IP address in Windows Firewall

Estimated reading: 3 minutes 381 views

Your Windows server has a Windows firewall which safeguards your system from malicious attacks. The firewall identifies if anything attempts to access your server and compares it with a set of rules. If it isn’t according to the rules or breaks the rules, your firewall doesn’t let the traffic through.
Your firewall can also block certain IP addresses from connecting to your server. On a Windows server, you do this by logging into your server via RDP and creating a new firewall rule listing the IP addresses you want to block.
In case you also want to block a specific IP in Windows Firewall, you will need to follow the below steps to achieve the best results.
