Isn't Comcast one of those few ISPs who are serious about IPv6? The configuration page looks like it is intended for native IPv6 not tunneling. I suggest you forget about the service for a bit and instead contact Comcast asking, how you should be configuring this router. If you can get native IPv6, that should give you a better end result than a tunnel.

Yeah, I too thought Comcast was handing out IPv6 addresses
