Re: One computer two different networks

[Steve <root () quicksilverscreen com>]

What does this thing actually do? The ad says it's a 'data diode'?!?!? 
That is not only impossible, it would be pointless. Is there an actual 
description of it on the website? That doesn't ramble on about optically 
isolating me from the bad scary data?

I don't care if your packets come in via an opticially isolated 
circuit, and electrically isolated circuit, or a positronic brain the 
packets still have to leave your machine to initate either a get or post 
request, and both still have the ability to send data to the 'internet end'.

If it's a small IDS or IPS or both, I still don't see any need for 
optical isolation.

I'm smelling snake oil.

Thanks,
Steve.
