•
You can specify that this Router will Initiate Connections, acting as a foreign agent (Yes), or only answer
them, acting as a home agent (No).
•
Tunnels are normally initiated On Demand; however, you can disable this feature. When disabled, the
tunnel must be manually established through the call management screens.
•
You can specify the Idle Timeout, an inactivity timer, whose expiration will terminate the tunnel. A value of
zero disables the timer. Because tunnels are subject to abrupt termination when the underlying datalink is
torn down, use of the Idle Timeout is strongly encouraged.

Encryption Support

Encryption is a method for altering user data into a form that is unusable by anyone other than the intended
recipient. The recipient must have the means to decrypt the data to render it usable to them. The encryption
process protects the data by making it difficult for any third party to get at the original data.

Motorola Netopia PPTP is fully compatible with Microsoft Point-to-Point Encryption (MPPE) data encryption for
user data transfer over the PPTP tunnel. Microsoft Windows NT Server provides MPPE encryption capability only
when Microsoft Challenge Handshake Authentication Protocol (MS-CHAP) is enabled. Motorola Netopia
complies with this feature to allow MPPE only when MS-CHAP is negotiated. MS-CHAP and MPPE are
user-selectable options in the PPTP Tunnel Options screen. If either the client or the server side specifies
encryption, then encryption becomes mandatory for both.
