Virtual Private Networks (VPNs) 5-17
Motorola Netopia
®
’s ATMP implementation suppor ts Data Encr yption Standard (DES) data encr yption for user
data transfer over the ATMP tunnel between two Motorola Netopia
®
Routers. The encr yption 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 suppor ts 128-bit (“strong”) encr yption 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 encr yption.
•
When you choose MS-CHAP as the authentication method for a PPTP tunnel, the Motorola Netopia
®
Router
will star t negotiating MS-CHAPv2. If the gateway or VPN adapter client you are connecting to does not
suppor t 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 suppor t 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 ser ver 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.
To set the parameters under which the Router will answer attempted VPN connections, select
ATMP/PPTP
Default Profile
and press Return. The ATMP/PPTP Default Profile screen appears.
