I made some progress:
Made a SSH connection to the router and used the Linux-Route2 for confirurating the Tunnel
ip tunnel add he-ipv6 mode sit remote 216.66.84.46 local 81.24.96.88 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:1f14:13aa::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr
The code modprobe ipv6 didn't work. (-ash: modprobe: not found)
Ping reply:

5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 11.326/14.712/18.309 ms
So the tunnel is working?
I can't ping other IPv6 addresses
How to setup the LAN side of the router en the LAN clients?
