You should look at the spec's of a hardware or firewall appliance. A hardware solution is nothing more than a self contained CPU, memory, and switch with the software contained in ROM for bootup. In reality, it is as much a software solution as running software on a PC - literally. They do not have anywhere near the power of a full blown PC. In other words, a hardware solution has nothing speacial. It relies on software just as any other device that uses a cpu. Software based solutions running on a PC are only as "weak or strong" as the CPU doing the processing.

So if you use a modern CPU and GB ethernet cards, you can do just as much or more than with a overpriced firewall appliance. In fact, I use Linux's iptables for my firewalls . I'm not limited to two interfaces.

If you are thinking that a hardware or firewall appliance is anything other than a "software" based solution, think again. When you turn them on they bootup just like a pc and load software, their os as well as app, just like a PC.
