Abstract

The application provides an IP access method of an SSL VPN. The method comprises the following steps: sending tunnel configuration information to an SSL VPN client on terminal equipment so that the SSL VPN client updates the tunnel configuration information to a built-in client on the terminal equipment; receiving a private network IP address of the built-in VPN client sent by the SSL VPN client, storing the mapping relationship of the private network IP address and a resource list corresponding to the SSL VPN client; receiving a resource access message which is sent by the built-in VPN client and corresponding to the SSL VPN client; judging whether an IP address of a to-be-accessed resource is in the resource list, returning a locally encapsulated data message to the built-in VPN client when the IP address of the to-be-accessed resource in the resource list. Through the adoption of the method provided by the embodiment of the invention, the terminal equipment can access the resource in an IP access mode of the SSL VPN in the system with high security.

Description

technical field

[0001] The present application relates to the technical field of network communication, in particular to an IP access method and device of SSL VPN. Background technique

[0002] The SSL VPN is a new type of VPN (Virtual Private Network, Virtual Private Network) technology that uses the SSL (Security Socket Layer, Secure Socket Layer) protocol to realize remote access. It is based on HTTPS (Secure Hyper Text Transfer Protocol, that is, the HTTP protocol that supports SSL), and uses the certificate-based identity authentication, data encryption, and message integrity verification mechanisms provided by the SSL protocol to realize remote Access intranet resources.

[0003] Usually, SSL VPN has three commonly used access methods, namely Web access method, TCP access method and IP access method. However, in some systems, due to permission issues, terminal devices cannot access intranet resources through SSL VPN IP access, causing inconvenience for users to acces...
