Last night, I discovered that Sonic supports IPv6 6RD. After some quick mucking around in pfSense, I successfully enabled it and was able to ping6 remote hosts from the gateway.
And then I found myself wondering: Why should I do this?
I know enough about IPv6 to know that it is much more than simply IPv4 with longer addresses. It has a bunch more options and capabilities and, with them, more opportunities for misconfiguration and network vulnerability. I have personal experience on networks whose IPv4 traffic and subnets were well managed and locked down, but IPv6 just floated right through.
I barely grok the firewall rules that let NAT and port forwarding work; there's no way I know enough about IPv6 to think about all the possible pitfalls and configure a gateway/firewall properly. So: Why should I enable IPv6? What advantages over IPv4 are waiting for me if I go to the trouble of learning and setting up IPv6 on my home LAN?
