Table 53 PPTP Server (continued)
LABEL | DESCRIPTION |
Auth Protocol | Select the Authentication Protocol allowed for the connection. Options are: |
| • PAP - Password Authentication Protocol (PAP) authentication occurs in clear |
| text and does not use encryption. It’s probably not a good idea to rely on this |
| for security. |
| • CHAP - Challenge Handshake Authentication Protocol (CHAP) provides |
| authentication through a shared secret key and uses a three way handshake. |
| • MSCHAPv1 - Microsoft CHAP v1 (MSCHAPv1) provides authentication |
| through a shared secret key and uses a three way handshake. It provides |
| improved usability with Microsoft products. |
| • MSCHAPv2 - Microsoft CHAP v2 (MSCHAPv2) provides encryption through a |
| shared secret key and uses a three way handshake. It provides additional |
| security over MSCHAPv1, including |
|
|
MPPE | If MSCHAPv1 or MSCHAPv2 is selected as an Auth Protocol, use the drop- |
Encryption | down list box to select the type of Microsoft |
| Options are: |
| • MPPE 40 bits - MPPE with 40 bit session key length |
| • MPPE 128 bits - MPPE with 128 bit session key length |
| • Auto - Automatically select either MPPE 40 bits or MPPE 128 bits |
