The point is to get IPv6 connectivity. So you put the tunnel on another router from the vendor of your choice. Then you connect the WAN port of your ASUS router to the tunnel router. Your ASUS router won't know the difference. This would setup a nice testing environment. I have personally used this setup in the past for such purposes. It worked quite nicely. This is the exact same technology the ASUS supports to provide IPv6 connectivity through some ISP's. Its a native feature of the router.Tunnels, Native and Passthrough are different. I don't know if they produce the same results. Security approach is different for sure.
