[0051] The specific implementation example is as follows:
[0052] The IP address of the real network card on the user side is 192.168.1.100, and it is ready to access server 1 through a tunnel, but server 1 requires that only users whose source address is 192.168.1.100 can access, that is, the IP address of the virtual network card on the user side should be 192.168.1.100 . Based on this, SSLVPN assigns a virtual IP address to the client: 192.168.1.100. However, this IP address conflicts with the real network card IP address of the client, and the tunnel cannot be used, so the client notifies SSLVPN of the conflict. SSLVPN generates a shadow IP 192.168.2.100 for the client according to the algorithm, and sends it to the client. At the same time, the SSLVPN records Association of these two IP addresses. Since there is no conflict between 192.168.2.100 and the client, the tunnel is established successfully. The user side initiates a resource request to server 1 through this tun...
