5.6. Configuring PPP (Point-to-Point) Settings
Authentication Methods
In most cases, the provider’s PPP servers supports all the allowed authentication methods. If a connection fails, the user should disable support for some methods, depending on the PPP server configuration.
- Use point-to-point encryption (MPPE)
- Microsoft Point-To-Point Encryption protocol (RFC 3078).
- Allow BSD data compression
- PPP BSD Compression Protocol (RFC 1977).
- Allow Deflate data compression
- PPP Deflate Protocol (RFC 1979).
- Use TCP header compression
- Compressing TCP/IP Headers for Low-Speed Serial Links (RFC 1144).
- Send PPP echo packets
- LCP Echo-Request and Echo-Reply Codes for loopback tests (RFC 1661).
Note
Since the PPP support in NetworkManager is optional, to configure PPP settings, make sure that the NetworkManager-ppp package is already installed.
