What are HARDWARE firewalls for?
A hardware firewall is just a separate box that sits between you and the internet world. If the box gets hacked or compromised, it's not carrying any valuable information, as that would be on a separate machine inside your network. Its useful in the corporate world, as it marshalls access on the internal network to and from another network (usually the Internet) for many computers.
Quite often these boxes use a version of Linux inside them, and they're using IPtables to provide the NAT firewall.
You can set up your own hardware firewall, all you need is an old computer and a distro like Smoothwall or shorewall. There is a list of them here: https://en.wikipedia.org/wiki/List_o..._distributions.
I use a smoothwall box at home.
Hardware firewalls typically will have more tools to simplfiy setting up a firewall and dynamicly optimizing rulesets based on traffic along with other features. Some of the expensive ones have customized TCP/IP stacks for better performance and vendor hooks. As Roxoff said for home or small office can easily get and old computer install Linux and Smoothwall and have a good firewall.
