Other than the hardware firewalls cost more?

Any low cost recommendations? I'm looking mostly for the firewall functions than anything else.

What should I look for and what would be most secure?

this is interesting

and this?

But would this have a better firewall than those above?

What about this one?

You'll forgive me (I hope) if I refer you to Wikipedia to explain the intricate details of both options:

Wikipedia: Routers
Wikipedia: Firewalls

That didn't really tell me much about these particular models, but to guess that as long as the router has NAT, block WAN ping, and SPI then it serves effectively as a firewall would not be wrong, would it?

A router, routes stuff in simple terms. It directs the traffic of your local network-you hook multiple computers to it and the internet, and when you send a command over the network it routes the traffic to the proper computer or over the internet. Its in essence a traffic gaurd. A firewall, is more like a cop in that it protects from unwanted outside connections. It attempts to block any unwanted traffic from getting into your computer or router. There are two kinds of firewalls-a physical firewall, like what most routers have which is in the circuitry, and a software firewall which you install on your computer, its often wise to use both.

I know. But some routers have firewalls, and then they have a separate section of hardware firewalls at newegg under networking. I'm finding it hard to tell the difference between the two.

Well at a basic level, routers differ from firewalls in a way that a router routes packets destined to another network. it is the gateway so that two or more networks could communicate with one another while a firewall on the other hand is more of a security device that inhibits inbound or outbound traffics base on the network's preferences.

you are able to use your services when using the router since this is what a router does it forwards your request to the appropriate destination, however, when using the firewall as your means of communication, although, it acts as a router, but its main features is security and in this case, by default, it has its security features on making sure that any traffic either inbound or outbound are filtered through it preventing your network from any harm from outside.

so a router with SPI and NAT is really just a hardware firewall with the settings set to favor convenience of use instead of security?
