Orange TV con router neutro Asus RT-AC66U_B

Hola,

Llevo en Orange apenas 4 semanas, estoy utilizando un router neutro(ASUS RT-AC66U_B) con el nuevo deco 4K, pero estoy teniendo problemas para ver los canales que van por IPTV(4K, FOX HD, Cosmo..) por lo que he averiguado hay que configurar el IGMP multicast en la interfaz WAN.... de echo un uuario de router mikrotik lo ha conseguido, pero no se adaptar la configuración al router asus.

La config de su router:

En mi router está configurado sobre ether1-gateway la salida a internet y sobre ether5-master-local el STB.

	/interface vlan
	add name=pool-red-200 ranges=192.168.200.10-192.168.200.100

Podrías echarme una mano con eso? por favor.

Muchas gracias
