1.L2TP the second-tier tunneling protocol is a way to access certificates. 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 certificat

the L2TP or PPTPVPN tunneling technology on IPSec. The SSL protocol for www.2cto.com SSLVPN provides features such as data privacy, endpoint verification, and information integrity. The SSL protocol consists of many sub-protocols, two of which are handshake protocol and record protocol. The handshake protocol allows the server and client to confirm each other be

security gateways between the start and end points of the tunnel. A VPN can be used to provide a VPN when a tunnel is used in combination with data confidentiality. The encapsulated data packet is transmitted within the tunnel of the network. In this example, the network is Internet. A gateway can be a perimeter gateway between an external Internet and a private network. Perimeter gateways can be routers, firewalls, proxy servers, or other security gateways. In addition, two gateways can be use

/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.Encapsulate the IP address header.

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

In the front I sent an article "Juniper Firewall diagram L2TP VPN Configuration", we learned from that article how to configure. But we know that the L2TP VPN is only connected to our L2TP VPN server, but it doesn't encrypt our data, and we know that IPSec's data is encrypted, and if the
