Another protocol for implementing vpn is ipsec. To be precise, ipsec is a framework composed of multiple protocols. Its implementation can be divided into the following four steps: 1. implement data stream filtering control (control by acl) 2. Security proposal (implementing the working mode, selecting the security protocol, verifying the algorithm, and selecting the consistency of the encryption algorithm if the esp protocol is used) 3. Create a security policy (acl + security proposal + ike ne
