What is a Firewall
The firewall is a security feature built into the Windows operating system. It allows you to control incoming connections from other computers or devices. It also helps prevent unauthorized access to your computer.
Firewalls are devices that protect networks from unauthorized access. They function by analyzing network traffic and blocking undesirable traffic while passing desirable traffic freely. You may have heard about firewalls being used to secure computers from hackers, viruses, and malware. However, many organizations use a firewall for security reasons. When building a home network, it’s often helpful to have a firewall installed.
Types of Firewalls
There are two types of firewalls: hardware-based and software-based. Hardware-based firewalls are generally built inside routers. In contrast, software-based firewalls run on servers or PCs. Software-based firewalls provide additional features over hardware-based firewalls.

Installing and Managing Firewall
In order to install a firewall, you’ll need to know the operating system running on each device. If you’re installing a firewall on a computer, you’ll likely want to install Windows Firewall (Windows 8 users should download and install Windows Defender). If you’re installing a software-based firewall, you’ll want to download the firewall application. Once you’ve downloaded the firewall program, follow its instructions to install it.
You can manage firewall settings using Windows PowerShell. First, type ‘PowerShell’ at the command prompt. Then enter ‘netsh advfirewall show allprofiles’. Here you can change the profile name, enable or disable rules, and set exceptions for specific apps, websites, and protocols.
You can also configure the firewall and monitor connection attempts using the Web UI. From here, select either Basic Settings or Advanced Settings. Select Network Security and then click Add Rule. Enter the information requested, including the rule action, protocol, port number, local IP address, remote IP address, description, and state.
Using Internet Connection Sharing
Internet connection sharing (ICS) allows you to share an internet connection between multiple computers, including laptops, desktops, and mobile phones. ICS helps you extend your internet service by making your internet service provider (ISP) think that you have more bandwidth than you actually do. By doing this, it reduces your bandwidth usage and cuts down on monthly data costs. All you need to do is connect the computers directly to the router instead of having them connected via modem or cable.
To use ICS, you first need to turn off internet sharing on the router. Next, you need to log in to the web interface of your router. Search for the option that says “Configure Wi-Fi”. Click on this and scroll down until you find the section called “Wi-Fi Internet Connection Share.” Disable the box next to the title “Share my internet connection.” Now turn on internet sharing again and reconnect your computer(s) to the router.
Using NAT Traversal
NAT traversal is a method of connecting a server to the internet that uses NAT. As opposed to NAT, NAT traverse does not require any configuration changes on the server side. Instead, it relies on the client side. The client connects to a public DNS server instead of the internal DNS server.
The downside of this method is that you cannot access content on the internet through a private LAN. Instead, you must go through the external IP address assigned by the ISP. Additionally, this method works only if the client supports it.
How To Configure a Firewall
To configure a firewall, you must first understand the types of networks to which the firewall will be applied and the types of traffic that will be allowed or blocked. Once you have a clear understanding of your network and traffic requirements, you can begin configuring your firewall.
When configuring a firewall, you will need to specify the following:
- The type of traffic to allow or block
- The source and destination of the traffic
- The port or application to allow or block
To use a firewall, you must first ensure that it is properly configured. Once the firewall is configured, you can then enable it and test it to ensure that it is functioning as expected.
How To Use a Firewall
After setting up the firewall and configuring it. It will work automatically at the time, it is needed. Since it is an automatic feature, so you do not need to manually activate it each time you need it. It will do everything and you do not need to worry.
