A firewall is a network security tool that controls incoming and outgoing web traffic and lets or blocks data packets based on a set of safety protocols. Its goal is to build a wall that viruses and hackers can’t get through.
Type of firewalls
Firewalls can be either software or hardware, but having both is best. Every computer has an application called a software firewall that is installed on it. It keeps an eye on traffic based on port numbers and applications. A hardware firewall is a piece of hardware that sits between your network and gateway.
- Next-generation firewalls (NGFW)
- Proxy firewalls
- Network address translation (NAT)
- Stateful multilayer inspection (SMLI)
How To Change NETGEAR Firewall Settings?
Firewalls from NETGEAR are made up of both hardware and software. In the hardware section, you can find NETGEAR firewalls that work better than most, and in the software section, you can find firewalls that you can customize to fit your needs. A firewall can’t protect against every kind of attack. For instance, you still have to run a virus checker on all of your machines and programs. A UTM Threat management tool can look for malware, viruses, and spam and get rid of it. A Home Router can’t do these things.

You don’t need to use the operating system on your computer to set up a NETGEAR firewall. If you use a wireless network with a NETGEAR router, you can change the firewall settings by going to the configuration page on the router. With this, you can block and allow wireless traffic and data coming in and going out. This will keep viruses and other bad things from getting into your computer.
- Open your web browser and type “192.168.0.1” into the address bar.
- Use your administrator name and password to get in. By default, “admin” is the name and “password” is the password.
- Click on “Security.”
- Click “Rules,” then “Firewall Rules.”
- Choose “Add” to add new permissions or restrictions, “Edit” to change how the ones you already have work, and “Delete” to get rid of any permissions or restrictions.
- To save your changes, click “Apply.”
How do I set up firewall rules on my NETGEAR DSL modem router?
By default, NETGEAR firewall rules block and stop anyone from getting into your local area network without your permission (LAN). But you might want to let devices or programs on your local area network (LAN) be accessed from afar. You can do this by adding an inbound or outbound firewall rule to your DSL modem router.
- Inbound firewall rules let people on the Internet get to LAN services. By default, your router stops all service requests from coming in.
- Outbound firewall rules stop LAN devices from being able to connect to the Internet. By default, your router lets all traffic leave your network.
To set up rules for your NETGEAR DSL modem router’s firewall:
- Start a web browser on a device that is connected to the network of your router.
- Type www.routerlogin.net or 192.168.0.1. A window for logging in appears.
- Type in your login name and your password.
The name of the user is admin. The password is set to password by default. Case matters when it comes to the user name and password.
It shows the BASIC Home page.
- Under Security on the left side of the screen, click or tap Firewall Rules.
The menu might be called Content Filtering on older devices.
- To add an incoming or outgoing service, click or tap the “Add” button.
- Choose from the list of Services.
If your service is not on the list, explain what a customized service is:
a. Click or tap Services > Add Custom Service from the menu on the left.
b. Give the new service a name.
c. Choose the type of protocol used by the service.
d. Enter the starting port and the ending port.
e. To add the new custom service, click or tap Apply.
- Choose an action to take with the packets for the service.
Note: You can set a schedule for your action to make rules happen at a certain time. See here for more information. How do I use the router’s web interface to set up a blocking schedule on my NETGEAR router?
- In the Send to LAN server field, type the IP address of the device or server on your LAN that will get the traffic that this rule covers, whether it’s coming in or going out.
- Choose a WAN Users can choose which packets fall under the rule based on the wide area network from which they came (WAN) IP number:
Any: This rule applies to every IP address.
Address range: This rule applies to IP addresses in a certain range.
Single address: This rule only applies to a single IP address.
- Choose a Log option to choose which packets that this rule affects will be logged:
Always: Always logs traffic, no matter if it fits your rule or not.
This option could come in handy when you are testing and fixing your rules.
Never: Never logs traffic, no matter if it fits your rule or not.
Match: Only records traffic that fits your rule.
Not Match: Only records traffic that doesn’t fit your rule.
- Tap or click Apply.

How to Disable the Netgear Router Firewall
- To do this, type the router’s address into the Web browser (the default is either 192.168.0.1 or 192.168.1.1).
- When prompted, type in the username and password. admin is the default username, and password is the default password.
- Choose Security > Rules from the main menu.
- Add a new rule for Inbound Services with the service name “ANY” and the action “ALLOW always.“
- Then, move the new rule up so that it is the first rule in the section called “Inbound Services.”
- Last, check the Enable column to make sure that this rule is turned on.
The firewall on the Netgear Router has now been turned off. This means that the internal network is no longer protected and can be attacked from the Internet.
