I once did a similar thing to a netgear "managed" switch setup in two VLANs. Experimenting, I setup a crossover cable between the two VLANs to see how real the separation was. My theory was that it would work like having two separate switches. I was wrong. It took down the whole network as if I had run a crossover back into a switch that wasn't partitioned. I don't know whether or not this is a bug or not, but it makes me wonder just how good this netgear managed switch is and if I should replace it with something better for my internal DMZ purposes.
