We could also have Firewalls that are hard to pass.
I do a lot of network related programming, and also manage networks. Till this day, I'm still not quite sure what a "firewall" is.
I suppose it's a bit like a brickwall, but made of fire instead of bricks.
More seriously, I suppose it's, roughly, any device or program that can be configured to restrict access to networked resources (either inbound or outbound), as opposed to a networked device accepting any and all requests without discrimination.

So if I lock down all ports except for one, and allow access to that port only with certain user names and the correct password for each one, that's a firewall?

I don't have any sources to back this up, but I presume that networking firewalls are named by analogy with the firewalls in automobiles. Those walls are between the engine and the cabin and are there to keep the two environments separate and prevent all that nasty stuff going on in the engine from messing with the people in the cabin (and in particular, to ensure that the significant heat generated by the engine doesn't make it into the cabin, hence "fire"wall). By analogy, a networking firewall exists between that nasty outer network and the inner network, and tries to sanitize everything that enters the inner network.

I guess any tool which allows you to do that is called a firewall?
