That's why I'm running dual stack ever since m0n0wall started supporting it. But unfortunately using the internet means ipv4, over a single NAT-ed ip. So, yes I need to learn some more on networking, and that means both ipv4 and ipv6.

So, to rephrase my question, any links to a good networking primer on both ipv4 and ipv6 are welcome.
