An enterprise Always On VPN deployment presents many opportunities to deploy LoadMaster products to provide scalability, fault tolerance, and deployment flexibility. The LoadMaster can be deployed to provide load balancing for the following Always On VPN infrastructure components.

  1. Routing and Remote Access Servers (RRAS) Servers – An Always On VPN deployment may require more than one RRAS server to provide redundancy or to increase capacity to service more VPN connections than a single server is capable of.
  2. Network Policy Server (NPS) Servers – To authenticate VPN connections, VPN servers are configured to forward authentication requests to an NPS server. Having more than one NPS server eliminates this single point of failure and may be required to support authentication for large scale deployments.
  3. Geographic Redundancy – Unlike DirectAccess, Always On VPN has no concept of “multisite” configuration. To provide geographic redundancy, multiple VPN servers can be configured in various locations using a single, common public hostname. VPN client connections can then be routed to the most preferred location.
