Understanding Windows Firewall

Windows firewall is a security feature built into microsoft windows operating systems. It works by monitoring incoming and outgoing network traffic and blocking unauthorized connections. In simple terms, it acts as a fence to protect your computer from potential threats.

To customize its rules, you need to create firewall rules. Firewall rules define what traffic is allowed to enter or leave your system and what traffic must be blocked. There are two types of firewall rules: inbound and outbound rules.

Inbound rules control traffic coming from external networks, whereas, outbound rules control traffic leaving your system. By creating firewall rules, you can safeguard your system and maintain the integrity of your network.

Before You Start

Adding a firewall rule to your windows system is important for security reasons. Before starting, check your user account control (uac) settings to ensure proper access. It’s also recommended to turn off your antivirus protection temporarily. This will prevent any interference between the firewall rule and the antivirus.

Finally, create a system restore point to ensure you can undo any changes if needed. These three steps should be taken seriously when adding a new firewall rule to protect your system from potential threats. Follow the guidelines above to complete this process smoothly and with ease.

Creating Windows Firewall Rules

Accessing and creating windows firewall rules can be a daunting task, but this step-by-step guide will simplify the process. Firstly, you need to access the firewall settings. Then, open the advanced settings and create a new inbound rule. You’ll have to choose the rule type and select programs, ports, or protocols.
