Client-initiated VPN

In client-initiated VPN, the LNS authenticates users through PPP authentication (PAP or CHAP). In CLI configurations, this is the PPP authentication configured on the VT interface.

Evenly distributing access requests initiated by clients using nodes' static IP addresses based on load balancing policies

The InfoEqualizer feature employs a domain name resolution mechanism that can dynamically allocate access requests initiated by clients using domain names to target nodes based on load balancing policies.

Forwarding access requests initiated by clients using a node's static IP address to another node after node failover

The InfoEqualizer feature employs a domain name resolution mechanism that can dynamically allocate access requests initiated by clients using domain names to other nodes after node failover.

Retaining online services of clients connected to a faulty node

The InfoEqualizer feature introduces dynamic IP addresses, which each corresponds to a dynamic domain name. If domain names are not resolved, when clients access a node using the node's IP address and the node becomes faulty later, this IP address can automatically "float" to another node.
