Support Microsoft CHAP Version 2 Select this check box if you are com-
municating with a peer that uses Microsoft CHAP Version 2 authentication protocol.
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. This section
allows you to select the encryption methods your gateway may use when negotiat-
ing with a PPTP server. Select all the methods if no information is available about
the server's encryption methods. Please note that PPP encryption can only be used
with MS-CHAP or MS-CHAP-V2 authentication protocols.

Require Encryption Select this check box to ensure that the PPP connec-
tion is encrypted.
Support Encryption (40 Bit Keys) Select this check box if your peer sup-
ports 40 bit encryption keys.
Support Maximum Strength Encryption (128 Bit Keys) Select this check
box if your peer supports 128 bit encryption keys.
PPP Compression The PPP Compression Control Protocol (CCP) is re-
sponsible for configuring, enabling, and disabling data compression algorithms on
both ends of the point-to-point link. It is also used to signal a failure of the com-
pression/ decompression mechanism in a reliable manner.
Figure 9-68: PPP Compression
For each compression algorithm, select one of the following from the drop down
menu:
 Reject Reject PPP connections with peers that use the compression algo-
rithm.
 Allow Allow PPP connections with peers that use the compression algo-
rithm.
 Require Ensure a connection with a peer is using the compression algorithm.
