dual lan ???

bridging/ics

connections to more than 1 network.

i told you when dual lan matters. i gave you 3 situations. you yell at me for answering your question. Maybe if you have half a brain you would realize that you cant use 2 physical connnections for the same program, and at the same time your internet connection is much, much slower than your lan connections so even if you could somehow get it to use both lan connections and bypass all the issues that it would create, you still would not see a speed increase in file sharing over the internet.
