I read the thread Firewalls about four or five posts deep and had to
make a general comment: Firewalls refers to a specific technology, and
therefore cannot be used to identify a router. Network Address
Translation does provide protection from external sources until it
itself is hacked into (turning off remote administration would make that
impossible). But it is NOT a firewall.
It is easy in this field to interchange terminology, but when you deal
with a customer, your terms have to be consistent. A firewall is a
device that filters incoming IP packets to allow or disallow access --
inbound or outbound.
You would not refer to wireless technology when talking about cordless
phones even though they operate on the same frequency. They are
cordless phones, not wireless devices. Could they be used as a data
transfer tool? Absolutely! With modifications to the components, it
could transfer data just as a wireless network card. But it is still a
cordless phone!
My 2 cents.
