SSL VPN

An SSL VPN connection consists of three parts: a VPN gateway, an SSL server, and an SSL client.
How it works: With an SSL VPN gateway instance created in the VPC, the VPN gateway is configured on the SSL server, and then an SSL client corresponding to the SSL server is created to implement communication between the SSL client and the VPC.

VPN Gateway

The VPN gateway is the egress gateway for the VPC to establish a VPN connection. The client communicates with the VPC through SSL VPN.

SSL Server

The SSL server is a service module in the VPN gateway that provides SSL services. It primarily encapsulates and decapsulates data packets. Therefore, in the VPN gateway, it is necessary to configure the SSL server for the local IP range, client IP range, and communication protocol, port, and algorithm.

SSL Client

The SSL client is connected through OpenVPN, which creates an SSL client and provides the client configuration file and certificate download feature. Two-way authentication is needed between the client and the server. Only an authenticated client can establish a communication connection with the server.
You can access RIO through any browser with built-in SSL as an SSL client. The client operating system supports Windows, MAC, and Linux (mainstream versions).
