Sangfor's IPSec/SSL VPN solutions offer load balancing and failover mechanisms to ensure high availability and optimal performance for remote users. Here's a breakdown of the likely functionalities:

Load Balancing:

    Multi-WAN Support: Sangfor firewalls or dedicated VPN gateways can be configured with multiple WAN connections. This allows for distributing VPN traffic across these connections, preventing overload on any single link and improving overall throughput for users.
    Session Persistence (optional): This advanced feature helps maintain user connections to the same VPN server during sessions, even when traffic is balanced across different WAN links. This can improve user experience by avoiding disruptions caused by re-authentication upon switching connections.

Failover Mechanisms:

    Primary/Secondary Link Configuration: A primary WAN connection can be designated for VPN traffic, with a secondary link acting as a backup. If the primary connection goes down, the system automatically fails over to the secondary link, minimizing downtime for remote users.
    Health Monitoring: Sangfor's firewalls or VPN gateways likely monitor the health of WAN connections. If a primary link fails, the system detects the issue and initiates the failover process seamlessly.
    Route Priority: This feature can be used to define the priority for different VPN paths (connections). Higher priority routes are used first, with lower priority ones acting as backups. This allows for intelligent failover based on factors like bandwidth or latency.
