Let me understand this correctly: this strategy works *because* you
use 6to4 addresses on your workstations. I suppose it would also work
if you used the /64 address block allocated by HE (or some other
delegated tunnel broker network), but that would mean packets would
return through the tunnel instead of through the IPv4 network.
