Tunnels behind a CPE and 4to6 NAT seem like bandaid fixes as they do not give the benefit of true end to end IPv6 connectivity in the sense of every device has a one to one global address mapping.
No, tunnels do give you one to one global IPv6 address mapping for every device. From a testing perspective, a tunnelbroker works just as if you had a second IPv6-only ISP. If you're fortunate enough to have a dual-stack ISP already, you can forgo tunneling altogether and just use an IPv6-capable border firewall. William Waites wrote:
I was helping my friend who likes Apple things connect to the local community network. He wanted to use an Airport as his home gateway rather than the router that we normally use. Turns out these things can *only* do IPv6 with tunnels and cannot do IPv6 on PPPoE. Go figure. So there is not exactly a clear path to native IPv6 for your lab this way.
Nobody is recommending the Apple router as a border firewall. It's terrible for that. But it's a ready-to-go tunnelbroker gateway. If your ISP can't deliver IPv6, tunneling is the clear path to building a lab. If you have a dual-stack ISP already, the clear path is to use an IPv6-capable border firewall. So you are in a maze of non-twisty paths, all alike :)
