Motorola Enterprise Series Routers, 6161252-00-01 manual ATMP/PPTP Default Profile

Virtual Private Networks (VPNs) 5-17

Motorola Netopia®’s ATMP implementation supports Data Encryption Standard (DES) data encryption for user data transfer over the ATMP tunnel between two Motorola Netopia® Routers. The encryption option, none or DES, is a selectable option in the ATMP Tunnel Options screen.

MS-CHAP V2 and 128-bit strong encryption

Notes:

•Motorola Netopia® Embedded Software Version 8.7.4 supports 128-bit (“strong”) encryption when using PPTP tunnels.

ATMP does not have an option of using 128-bit MPPE. If you are using ATMP between two Motorola Netopia® Routers you can optionally set 56-bit DES encryption.

•When you choose MS-CHAP as the authentication method for a PPTP tunnel, the Motorola Netopia® Router will start negotiating MS-CHAPv2. If the gateway or VPN adapter client you are connecting to does not support MS-CHAPv2, the Motorola Netopia® Router will fall back to MS-CHAPv1, or, if the gateway or VPN adapter client you are connecting to does not support MPPE at all, the PPP session will be dropped. This is done automatically and transparently.

ATMP/PPTP Default Profile

The WAN Configuration menu offers a ATMP/PPTP Default Profile option. Use this selection when your Router is acting as the server for VPN connections, that is, when you are on the answering end of the tunnel establishment. The ATMP/PPTP Default Profile determines the way the attempted tunnel connection is answered.
