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.
