Routers and software firewalls overlap in some ways, but each provides unique benefits. It’s important to use at least one type of a firewall – a hardware firewall (such as a router) or a software firewall. This also prevents users from changing them on their computers. If you run a large network, you can easily configure the firewall’s settings from a single device. Hardware firewalls can provide centralized network management.However, that worm couldn’t disable your hardware firewall. A hardware firewall sits apart from your computer – if your computer becomes infected with a worm, that worm could disable your software firewall.

This feature is easy to use with a third-party firewall, but you can also prevent applications from connecting to the Internet with the Windows firewall. In addition to controlling incoming traffic, a software firewall can prompt you when an application on your computer wants to connect to the Internet and allow you to prevent the application from connecting to the network. Software firewalls allow you to easily control network access on a per-application basis.

If other computers on your network become infected, the software firewall can protect your computer from them.

A hardware firewall sits between your computer and the Internet, while a software firewall sits between your computer and the network.

(Although this feature may not be present on some routers.)

Both can block certain types of outgoing traffic.

Both block unsolicited incoming traffic by default, protecting potentially vulnerable network services from the wild Internet.

Hardware and software firewalls overlap in some important ways: If you’re connecting your computer directly to the Internet, it’s important to use a software firewall – you shouldn’t have to worry about this now that a firewall comes with Windows by default. Because software firewalls run on your computer, they can monitor which applications want to use the Internet and block and allow traffic on a per-application basis. Windows itself includes a built-in software firewall, which was first enabled by default in Windows XP Service Pack 2 (SP2). It acts as a gatekeeper, allowing some traffic through and discarding incoming traffic. Image Credit: webhamster on Flickr How Software Firewalls WorkĪ software firewall runs on your computer. A DMZ, in effect, forwards all traffic to a specific computer – the computer will no longer benefit from the router acting as a firewall. You can have the router forward some traffic by setting up port-forwarding or putting a computer in a DMZ (demilitarized zone), where all incoming traffic is forwarded to it. Depending on your router, you may also be able to block specific types of outgoing traffic by changing your router’s settings. In effect, the NAT acts as a firewall that prevents incoming requests from reaching your computer. When incoming traffic from the Internet reaches your router, your router doesn’t know which computer to forward it to, so it discards the traffic. Home routers use network address translation (NAT) to share a single IP address from your Internet service provide among the multiple computers in your household.
