Honestly, I don't think the router even supports IPv6 over IPv4 services like HE.net IPv6 Tunnelbroker. The interface you see is not for the configuration of IPv6 over IPv4. It seems to be the interface for a native IPv6 configuration granted your ISP has native IPv6 or you are able to obtain native IPv6 somehow else. The router doesn't even seem to support IPv6 over IPv4 in terminal as I cannot find any hints in its documentation.
You can most likely forget IPv6 over IPv4 with that router.
