10.2.2.2 PPP Encryption
PPP supports encryption facilities to secure the data across the network connection. A
wide variety of encryption methods may be negotiated, although typically only one method
is used in each direction of the link. Note that PPP encryption can only be used with MS-
CHAP or MS-CHAP-V2 authentication algorithms.

used to signal a failure of the compression/ decompression mechanism in a reliable
manner. For each compression algorithm, select one of the following from the drop down
menu:
