I recently got ipv6 going using toastman's firmware and using he.net 6in4 tunnel. I'm using the ddns he.net entry to update my dynamic ip. It appears to be working because I have ipv6 access when rebooting the router, and visiting he.net shows that it has my most current ip address. The only issue is that the router doesn't appear to know it succeeded because it return 'Unknown response (-1). ' and automatically tries to retry later. Have I done things right since it seems to be working? Is this just a bug with the ddns updater?
