Doh! OK, I'll buy that. I'd really (in my own way) seen firewalls as being
more like band-pass filters. But that's probably another discussion. When
I wrote "switch" I was really thinking "router."


It really did seem that he was suggesting that the firewall actually
actively route, as opposed to "look at the packet and drop it if it doesn't
like it . . ." ;-] So, I really meant to use the term router. That is a
step beyond the "throw it in the bit bucket if I don't like it" function
that is is a better fit for what mjr seemed to be describing. Of course, I
don't want to put words in his mouth . . . ;-)
