Hello all, here is what I am looking for. Something that
I can basically turn off my network connection into my
computer at the touch of a button. I have DSL and would
basically like to have a button that I can push to
essentially act like a dial up....push the button on, push
again off (secured). Anything like that out there? Also,
while on the subject. I am currently building a firewall,
so I have 2 Cat5 cables that I use....one for the domain,
and one for internet. It is a pain to switch them back
and forth. Anything that could help me out with that out
there? Thank you all in advance.
