Unable to reach internet using IPv6 network for LAN

This article covers a use case scenario should a customer receive a block of IPv6 global IPs and decides to subnet it for their LAN network.
Service Provider filters traffic on edge routers using prefix-list, since BGP consumes an important amount of CPU, so they filter advertisement routes from client, and packets that don't match the prefix-list are dropped. This means if we do a packet capture on the SonicWall we will be able to see upstream traffic coming from LAN subnet but there is no downstream traffic.
