Hi,
By default, DirectAccess accept a /64 prefix for the IP-HTTPS range on a single server.
This is the IPv6 range for your clients.
When moving to NLB, you must use a /59 range because each DirectAccess server in the Cluster will receive a /64 range based on the range you defined in the console.
Let's say you implement a 2001::1000:/59, server1 will use 2001::1000:/64 for the clients, server2 will use 2001::1001:/64, etc...
