Always On VPN is Microsoft’s replacement for DirectAccess. This New remote Access technology was introduced in Windows Server 2016 and Windows 10 client.
It aims to address several shortcomings of DirectAccess such as support for non-Domain devices for example.
Load balancing Always On VPN
Remote access is vital to organisations of any size and any level of downtime is not acceptable. Edgenexus offers 3 key advantages for load balancing a Microsoft Always on VPN environment.
Data center resiliency and Geolocation load balancing
Load balancing VPN servers
RADIUS server resiliency

RADIUS server resiliency
Always On VPN uses certificates for Authentication. The Authentication Protocol favored is the EAP (Extensible Authentication Protocol).
Client requests are authenticated using a RADIUS server and these can be load balanced using the EdgeNexus load balancer. Typically the NPS (Network Policy Servers) server can be load balanced to provide resilience and scalability.
