Evidently I'm behind a firewall, beacause I have the brick wall icon.

I am using Mac OS X, and my firewall is OFF, and always has been since day one.

As far as I know I am not using a router. I just have a simple Qwest DSL modem with wireless gateway. (What is wireless gateway? Is it some sort of router, or firewall?)

Everything seems to work fine. I get all 5 green bars, and I can download things fairly well (24-25kbs).

So I guess I want to know, what's causing the brick wall? Should I be concerned?

Thanks in advance
