Main Mode: In main mode, the identification information for authentication is encrypted, thus enhancing security.Īggressive Mode: In aggressive mode, less packets are exchanged, thus improving speed. You can specify the exchange mode as main mode or aggressive mode. The exchange mode determines the way VPN routers negotiate in IKEv1 Phase-1. Initiator Mode: In initiator mode, the VPN router sends requests for IKEv1 negotiation and acts as the VPN client or the initiator. Responder Mode: In responder mode, the VPN router responds to the requests for IKEv1 negotiation and acts as the VPN server or the responder. You can specify the negotiation mode as responder mode or initiator mode. The negotiation mode configured for IKEv1 Phase-1 negotiation determines the role that the VPN router plays in the negotiation process.

Specifically speaking, it refers to hash algorithm, symmetric encryption algorithm, asymmetric encryption algorithm applied in IKEv1 Phase-1, and security protocol, hash algorithm, symmetric encryption algorithm applied in IKEv1 Phase-2. Proposal is the security suite configured manually to be applied in IPsec IKEv1 negotiation. The basic concepts of IPsec are as follows: IKEv1 negotiation includes two phases, that is IKEv1 Phase-1 and IKEv1 Phase-2. IPsec uses IKEv1 (Internet Key Exchange version 1) to handle negotiation of protocols and algorithms based on the user-specified policy, and generate the encryption and authentication keys to be used by IPsec. IPsec (IP Security) can provide security services such as data confidentiality, data integrity and data origin authentication at the IP layer. TL-R600VPN V3 or below doesn’t support L2TP. TP-Link SafeStream VPN Routers support Layer 2 tunneling protocol (PPTP, L2TP) and Layer 3 tunneling protocol (IPsec). The following figure shows the typical network topology in this scenario. Client-to-LAN VPN can satisfy this demand. For example, an employee on business can access the private network of his company securely. In this scenario, the remote host is provided with secure access to the local hosts. LAN-to-LAN VPN can satisfy the demand that hosts in these private networks need to communicate with each other. For example, the private networks of the branch office and head office in a company are located at different places. In this scenario, different private networks are connected together via the internet. Common tunneling protocols are Layer 2 tunneling protocol and Layer 3 tunneling protocol.ĭepending on your network topology, there are two basic application scenarios: LAN-to-LAN VPN and Client-to-LAN VPN. The core of VPN is to realize tunnel communication, which fulfills the task of data encapsulation, data transmission and data decompression via the tunneling protocol. Private indicates users can establish the VPN connection according to their requirements and only specific users are allowed to use the VPN connection. Virtual indicates the VPN connection is based on the logical end-to-end connection instead of the physical end-to-end connection.

VPN (Virtual Private Network) provides a means for secure communication between remote computers across a public WAN (Wide Area Network), such as the internet.
