Whilst we'd always recommend a hardware-based firewall (which can be built-in to your router and configures your broadband connection for your PC and any other PC connected to your network), some of us only have a basic broadband modem, supplied by our ISP. The next best alternative is to install a strong software-based firewall such as Jetico Personal Firewall 2.0, which is currently available as a public beta.
There's no stopping you installing both a hardware and software firewall on the same network. Indeed, you might find that you use one basic PC as a 'download box' and you need various P2P ports open on your hardware firewall so you can download files. However, on your work PC you might want to prevent unauthorised external access through any of your ports. In this instance, you'd use your software firewall to close all incoming ports on your work PC.
Whatever your scenario, we provide the options and we're sure you'll decide what's best for your network. Take a look at Jetico Personal Firewall 2.0 and that should give you all you need for a free software firewall.
