Thursday 17th May 2012: 11.46pm. Just upgraded our #pfSense firewall to 2.1 dev which has shiny new IPv6 support. Turns out, fairly amazingly, that my ISP Imagine Ireland (part of Irish Broadband) supports native #IPv6 via 6to4, so all you have to do is tell pfSense to use 6to4 and voila, every machine in your network gets its own, real IPv6 address. Unlike with using a 6to4 tunnel from say tunnelbroker, 6to4 requires zero configuration.
Here's how with pfSense 2.1: Go to WAN config page. Choose "6to4" as the IPv6 configuration type. Go to LAN config page. Choose "Track Interface" as the IPv6 configuration type. Make sure it's tracking the WAN interface. Apply the settings. Within a few minutes, all IPv6 capable devices will automagically gain a real IPv6 address.
And for proof:
