A system designed to prevent unauthorized access to or from a private

My Watchguard FW appliance can do every last bit of what is in that link.
My Linksys NAT router couldn't do every last bit of what is in that link.

Actually the firewall definition part in that text probaly the
nat-router does do i all cases however it's not that good written:

An Internet firewall examines all traffic routed between your network
and the Internet to see if it meets certain criteria. If it does, it
is routed between the networks, otherwise it is stopped. A network
firewall filters both inbound and outbound traffic.

The rest of the text is more or less optional, else a firewall has to
be an packet filter, and I can think of several possible firewalls
that isn't packetfilters at all. What do you think of the more common
definition of firewall: "A system designed to prevent unauthorized
access to or from a private network."

With that definition it's more easy to define what is and what isn't
a firewall. A firewall isn't always one maching, och pice of hardware.
Othen it's a combination of several different pices of hardware and
software.

And the system can a combination of solutions such as routers, FW
appliances and computer host based solutions.

Can then the router without the other stuff be a firewall? If it has
some parts of the outside or inside network routed into a black-hole?

Agreed for the most part and it *is* worth less in other situations.

Jepp, but if could be a good woring part of the firewall if you have
secure machines on the inside. It might be a good firewall then.
