Tunnel on openelec

[graploos]

I'm trying to configure a tunnel on openelec but i can't seem to get it to work.
Ifconfig doesn't seem to accept the inet6 command.

If i try ip tunnel add he-ipv6 mode sit remote 216.66.84.46 local myipv4 ttl 255 i just get the ip help info.

Could anyone help me out?
