Working with Remote Access VPNs for PPTP

PPTPPoint-to-Point Tunneling Protocol. PPTP is a method for implementing virtual private networks. It uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.is an alternative toL2TPLayer-2 Tunneling Protocol. L2TP is a networking protocol used by the ISPs to enable VPN operations./IPsecInternet Protocol security. IPsec is a protocol suite for secure IP communications that authenticates and encrypts each IP packet in a communication session.. LikeL2TPLayer-2 Tunneling Protocol. L2TP is a networking protocol used by the ISPs to enable VPN operations./IPsecInternet Protocol security. IPsec is a protocol suite for secure IP communications that authenticates and encrypts each IP packet in a communication session.,PPTPPoint-to-Point Tunneling Protocol. PPTP is a method for implementing virtual private networks. It uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.provides a logical transport mechanism using tunneling or encapsulation to sendPPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression.frames across an IP network.PPTPPoint-to-Point Tunneling Protocol. PPTP is a method for implementing virtual private networks. It uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.relies on thePPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression.connection process to perform user authentication and protocol configuration.

WithPPTPPoint-to-Point Tunneling Protocol. PPTP is a method for implementing virtual private networks. It uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets., data encryption begins afterPPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression.authentication and connection process is completed.PPTPPoint-to-Point Tunneling Protocol. PPTP is a method for implementing virtual private networks. It uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.connections are encrypted throughMPPEMicrosoft Point-to-Point Encryption. A method of encrypting data transferred across PPP-based dial-up connections or PPTP-based VPN connections., which uses theRSARivest, Shamir, Adleman. RSA is a cryptosystem for public-key encryption, and is widely used for securing sensitive data, particularly when being sent over an insecure network such as the Internet.RC-4 encryption algorithm.PPTPPoint-to-Point Tunneling Protocol. PPTP is a method for implementing virtual private networks. It uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.connections require user-level authentication through aPPPPoint-to-Point Protocol. PPP is a data link (layer 2) protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression.-based authentication protocol (MSCHAPv2 is the currently-supported method).

A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions.命令配置PPTPPoint-to-Point Tunneling Protocol.
