If you are on Vumatel Trenched you will need a 6in4 tunnel, which is just a ticket away to get the details of. If you are not on Vumatel Trenched, @websquadza will help you out there.IPv6
My router settings, what is required of Web Squad.
I'm new to this.
Edit: I see you are Vumatel Trenched, if you already have your details you can just select "Tunnel 6in4" and fill in the fields with what WebSquad has given you. If you don't have any tunnel details, you're going to have to ticket to get them (P.S. if you include your router model in the ticket, @websquadza will give you the exact steps you need to take to set it up).
