In the L2TP over IPSec application scenario, the USG device encrypts the original data packet with IPSec and then encapsulates the packet with L2TP.
The principle of HTTPS Flood source authentication defense is that the Anti-DDoS device replaces the SSL server with the client to complete the TCP three-way handshake. If the TCP three-way handshake is complete, the HTTPS flood source authentication check is successful.
A user SSL VPN authentication succeeds. The network extension is enabled on the PC. The assigned address has been obtained. The user PC cannot access the resources of the intranet server. Possible reasons?
112. The ESP only verifies the IP payload and can perform NAT traversal, but the ESP encrypts the Layer 4 port information and causes the PAT function to be unusable. This problem can be solved by using the IPSec transparent NAT function, which encapsulates the ESP packet in the UDP header and comes with the necessary port information to make the PAT work normally.
