What is PPP protocol?
PPP is a remote access protocol that allows you to implement TCP/IP. It establishes a connection via point-to-point links (i.e., dedicated leased lines and dial-up). PPP is used most often for remote connections to LANs and ISPs. PPP utilizes the Link Control Protocol (LCP), which tests the link between client and PPP host ...
How to use PPTP?
To use PPTP, you’ll have to set up a PPP session between the server and the client, usually over the internet. Once the session is established, you’ll create a second dial-up session. This dial-up session will use PPTP to dial through the existing PPP session.
What is LCP in PPP?
PPP utilizes the Link Control Protocol (LCP), which tests the link between client and PPP host and specifies PPP client configuration, to communicate between host and PPP client. LCP allows PPP to support authentication negotiation, in addition to compression and encryption negotiation between the client and the server, using encryption control protocols (ECPs) and compression control protocols (CCPs). PPP can support multiple network protocols by using protocol-specific network control protocols (NPCs). Because it can run over numerous physical media types and features error-checking functionalities, PPP has almost entirely replaced SLIP.
