Movistar FTTH (internet + VOIP) using an OpenWRT router

In essence, you need to do this:

1. Tag outgoing data packets with VLAN ID 6
2. Tag outgoing VOIP packets with VLAN ID 3
3. Set a PPPoE WAN interface over VLAN 3
4. Configure forwarding from LAN to VOIP
5. Id. from LAN to WAN, as usual
6. Have some good luck to spare :)
