Let me say up front I'm not very knowledgeable about v6 yet. One reason I don't want to enable it is the exact flip side of the address scarcity of v4. Because of that, external connections are nat'd. That seems to me to offer an additional layer of protection for devices on my network, they don't have externally routeable addresses. I think that is not true if I turn on v6. Is this correct?
