Field Description
PPTP Client Configuration
MS-CHAPv2
Enables or disables support for MS-CHAPv2 authentication method. Introduces an additional
feature not available with MSCHAP or standard CHAP authentication: the change password
feature. This feature lets the client change the account password if the RADIUS server reports
that the password has expired. Choices are:
• Checked = enable support for MS-CHAPv2.
• Unchecked = disable support for MS-CHAPv2.
Encryption Supported
Mppe 40 bit
Enables or disables MPPE 40-bit encryption (available only for MS-CHAP and MS-CHAPv2
authentication methods). Choices are:
• Checked = enable MPPE 40-bit encryption.
• Unchecked = disable MPPE 40-bit encryption.
Mppe 128 bit
Enables or disables MPPE 128-bit encryption (available only for MS-CHAP and MS-CHAPv2
authentication methods). Choices are:
• Checked = enable MPPE 128-bit encryption.
• Unchecked = disable MPPE 128-bit encryption.
Stateful Mppe
Enables or disables stateful MPPE encryption (available only for MS-CHAP and MS-CHAPv2
authentication methods). Stateful encryption provides the best performance, but may be
adversely affected by networks experiencing substantial packet loss. If you choose stateful
encryption, configure flow control (SETUP > QoS > LAN QoS > Flow Control ) to minimize the
detrimental effects of this lossiness. Choices are:
• Checked = enable stateful MPPE encryption.
• Unchecked = disable stateful MPPE encryption.
User Time-out
Idle TimeOut
If there is no traffic from a user for more than the specified time out, the connection is
disconnected. Entering an Idle TimeOut value of 0 (zero) means never log out.
