-1. Logon to your pfSense box and add the following file to `/cf/conf/att_dhcp6.conf` changing the WAN / LAN interface names to match your setup:
-```
-# WAN
-interface ngeth0 {
-        send ia-na 1;   # request stateful address
-        send ia-pd 1;   # request prefix delegation - LAN
-        request domain-name-servers;

 **LAN Setup**
 
 1. Go to _Interfaces > LAN_
 1. Change the **IPv6 Configuration Type** to _Track Interface_
 1. Under Track IPv6 Interface, assign **IPv6 Interface** to your WAN interface.
-1. Configure **IPv6 Prefix ID** to _0_
+1. Configure **IPv6 Prefix ID** to _1_. We start at _1_ and not _0_ because pfSense will use prefix/address ID _0_ for itself and it seems AT&T is flakey about assigning IPv6 prefixes when a request is made with a prefix ID that matches the prefix/address ID of the router.
 1. Save
 
+If you have additional LAN interfaces repeat these steps for each interface except be sure to provide an **IPv6 Prefix ID** that is not _0_ and is unique among the interfaces you've configured so far.

 **DHCPv6 Server & RA**
 
 1. Go to _Services > DHCPv6 Server & RA_
 1. Enable DHCPv6 server on interface LAN
-1. Configure a range of ::1000 to ::2000
+1. Configure a range of ::0001 to ::ffff:ffff:ffff:fffe
 1. Configure a **Prefix Delegation Range** to _64_
-1. Add a few IPv6 DNS servers
