PPP concepts

You can use PPP to connect a System i™ platform to remote networks, client PCs, another System i platform, or an Internet service provider (ISP). To fully use this protocol, you should understand both the capabilities and the i5/OS^® support for this protocol.

• What is PPP
  Point-to-Point Protocol (PPP) is a TCP/IP protocol that is used to connect one computer system to another. Computers use PPP to communicate over the telephone network or the Internet.

• Connection profiles
  Point-to-Point connection profiles define a set of parameters and resources for specific Point-to-Point Protocol (PPP) connections. You can start profiles that use these parameter settings to dial-out (originate) or to listen for (receive) PPP connections.

• Group policy support
  With group policy support, network administrators can define user-based group policies to manage resources. Individual users can be assigned access control policies when they log on to the Point-to-Point Protocol (PPP) or Layer Two Tunneling Protocol (L2TP) session.
