Enabling Your Wireless Router’s Built-in Firewall

(Last Updated On: December 23, 2017)

Your wireless router is probably the most over looked gadget in your home once you buy it and settle it in some old dusty space you will probably not bother about it until you see a performance decline in your Internet Connectivity or you just want to see goodbye to the old dusty router. But if you pay more attention to it’s features you’d probably get more out of your wireless router.

Most wireless routers today come with a built-in firewall that is often looked over and not paid much attention to. A firewall is a very important part of your wireless network’s security and is essential in warding off unauthorized access to your network. A built-in firewall may have been there in your wireless router and you might not have realized it. In this publication we are going to show you how you can utilize wireless router’s firewall and enable it to protect your network. Let’s get into it.

What is a Firewall? Why Would I Need It?

A firewall is a digital filter that monitors and creates a check and balance of the network boundaries. The firewall is responsible for granting access to the packet data for it to leave or enter the network premises.

There are two types of firewalls that you will mostly encounter.

  • Software Based Firewall
  • Hardware Based Firewall

The firewall that we have installed in our PCs is usually software based firewall while the one we are discussing here, the built-in firewall in wireless routers is the hardware based one.

Wireless router’s NAT (Network Address Translation) is basically the one doing all the work, you get a single IP address from your ISP that is shared among your devices. The NAT receives the incoming traffic from the router and it acts as a firewall if the traffic is unauthorized or malicious. The NAT also serves the purpose of blocking outgoing traffic as well that depends on how you configure your wireless router’s firewall.

How To Check If Your Wireless Router Has a Firewall?

No matter which wireless router you own the access to it’s internal admin panel is through a non-routable internal IP address which is usually in the form of 192.168.1.1 or something similar to this.

You have to open your browser and type in the IP address in the address bar that will lead you to the admin panel of your Wireless Router. To find out your wireless router’s admin panel’s IP address you should consult the user manual or you can visit your router’s manufacturer’s website for more support. To my knowledge these are some of the IP addresses that may work for most of the models produced by these manufacturers. If it doesn’t work with your wireless router please consult the user manual.

  • Linksys – 192.168.1.1 or 192.168.0.1
  • D-Link – 192.168.0.1 or 10.0.0.1
  • Apple – 10.0.1.1
  • ASUS – 192.168.1.1
  • Buffalo – 192.168.11.1
  • NETGEAR – 192.168.0.1 or 192.168.0.227

Once you login the admin panel using your username and password you have to look for a tab or page labelled “security” or “firewall” that will confirm that your wireless router do have a built-in firewall.

How To Enable Firewall On Your Wireless Router?

Once you have opened the Security or Firewall page or tab then you have to look for an option labelled “SPI Firewall” or just “Firewall” you have to enable that option and save the settings. After that click on apply for the changes to take effect. Your router will reboot itself and your firewall is enabled.

After enabling your firewall you have to go back in the admin panel and configure your firewall and you can configure it according to your requirements. After you have configured it, test your firewall to make sure it is working as it should.
