I'm not sure how you plan to manage your /48, but this is how I've seen it done in the past: 1) You are given a single IPv6 address (a /128) for your Internet-facing router. You are expected to add this address to your untrusted interface. You are also given the address of a router at your ISP which is your IPv6 default route. 2) You are also given a block of addresses. In my case this case a /64, although it should work for any size prefix. You are expected to hand these addresses out on your trusted interface via either DHCPv6 or SLAAC (depending on your preference). Assign one of the addresses in the block to your router's LAN interface and supply this as the default route for your LAN hosts. Good luck. On Jan 10, 2015 10:10 AM, "F.
