Netopia Firmware 4000-Series - Manual (Page 113)

Virtual Private Networks (VPNs) 4-11
MS-CHAP V2 and 128-bit strong encryption
Notes:
■ The Netopia Firmware Version 5.4 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 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 Netopia router will star t
negotiating MS-CHAPv2. If the router or VPN adapter client you are connecting to does not suppor t
MS-CHAPv2, the Netopia router will fall back to MS-CHAPv1, or, if the router 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.
