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.
Return to the Connection Profile screen by pressing Escape.
Select IP Profile Parameters and press Return. The IP Profile Parameters screen appears.
Enter the Remote IP Address and Remote IP Mask for the host to which you want to tunnel.
Encryption Support
Encr yption 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 decr ypt the data to render it usable to them. The encr yption 
process protects the data by making it difficult for any third par ty to get at the original data.

 PPTP is fully compatible with Microsoft Point-to-Point Encr yption (MPPE) data encr yption for 
user data transfer over the PPTP tunnel. Microsoft Windows NT Ser ver provides MPPE encr yption 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 ser ver side specifies 
encr yption, then encr yption becomes mandator y for both.
