, pay attention to the network conditions between two encrypted tunnels. If there is a high latency or a large number of packet loss, select TCP as the underlying protocol, due to the absence of connection and retransmission mechanisms, UDP protocol is inefficient because it requires the upper-layer protocol to be retransmitted. OpenVPN is a pure application-layer VPN protocol based on SSL encryption. It is a type of ssl vpn and supports UDP and TCP (Note: UDP and TCP are two communication proto

Microsoft's point-to-point encryption algorithm MPPE. It creates a VPN over a TCP/IP-based data network to implement secure data transmission from a remote client to a dedicated Enterprise Server. PPTP supports creating on-demand, multi-protocol, and virtual private networks through public networks (such as the Internet. PPTP allows encrypted IP communication, and then encapsulates it in the IP header sent across the company's IP network or public IP

security system. Also on the network, the advantages and disadvantages of various VPN protocols are benevolent, wise, and wise. For the purpose of use, many technical staff, including access control, security, and ease of use, flexible expansion and other aspects, weigh the advantages and disadvantages, it is difficult to choose; especially in the VOIP voice environment, network security is particularly important, so more and more network calls and voice gateways support VPN protocol.

You need to install a certificate Server in the VPN server intranet, and then have the VPN server trust the certification authority, and then publish the Certificate Server and download the certificate.

access protection (NAP) forces the client to have no response. Some network services or resources may be unavailable. If the problem persists, disconnect and try again. Access the connection, or contact the administrator who remotely accesses the server. 823The received encrypted binding TLV is invalid. 824The encrypted binding TLV is not received. 825Point-to-Point Tunneling Protocol (PPTP) is incompatible with IPv6.

SSL: Specifies a Data Security score between the Application Protocol (HTTP, telnet, nntp, FTP) and TCP/IP. Layer mechanism. Provides data encryption, server authentication, message integrity, and optional client authentication for TCP/IP connections. .Difference between SSL and TLS: TLS can be seen as an upgraded version of SSL. The main difference is that the supported encryption algorithms are different. SSH: SSH is a protocol used for secure remot

Application Introduction L2TP VPN PC to site mode can provide terminal access to the security tunnel of the Headquarters network. If you are on a business trip, you can connect to the Internet, use the terminal's own VPN client dial-up connection, and establish a secure tunnel for data transmission.
