itself a compression protocol. 
Note: The Netopia R6000 Series Routers suppor t 128-bit (“strong”) encr yption and MS-CHAP Version 2. Unlike 
MS-CHAP version 1, which suppor ts one-way authentication, MS-CHAP version 2 suppor ts mutual 
authentication between connected routers and is incompatible with MS-CHAP version 1 (MS-CHAP-V1). When 
you choose MS-CHAP as the authentication method for the PPTP tunnel, the Netopia Router will star t 
negotiating MS-CHAP-V2. If the router you are connecting to does not suppor t MS-CHAP-V2, it will fall back to 
MS-CHAP-V1, or, if the router you are connecting to does not suppor t MPPE at all, the PPP session will be 
dropped.
You can specify a Send Host Name which is used with Send Secret for authenticating with a remote PNS 
when the profile is used for initiating a tunnel connection. 
You must specify a Send Secret (the CHAP term for password), used for authenticating the tunnel when 
initiating a tunnel connection.
You can specify a Receive Host Name which is used with the Receive Secret for authenticating a remote 
PPTP client.
You must specify a Receive Secret, used for authenticating the remote PPTP client.
You can specify that this router will Initiate Connections (acting as a PAC) or only answer them (acting as a 
PNS).
Tunnels are normally initiated On Demand; however, you can disable this feature. When disabled, the 
tunnel must be manually established via the call management screens or may be scheduled using the 
scheduled connections feature.
Some networks that use Microsoft Windows NT PPTP Network Ser vers require additional authentication 
information, called Windows NT Domain Name, when answering PPTP tunnel connection requests. Not all 
Windows NT installations require this information, since not all such installations use this authentication 
feature. The Optional Windows NT Domain Name is not the same as the Internet domain name, but is the 
name of a group of ser vers that share common security policy and user account databases. Your PPTP 
tunnel par tner’s administrator will supply this Windows NT Domain Name if it is required.
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.
An alternate way to force a tunnel to stay up is to define a forced up scheduled connection for the profile. 
The method works the same way as creating a forced up scheduled connection for the line backup feature.
