5-6  Firmware User Guide
Netopia Firmware Version 8.6.1 suppor ts 128-bit (“strong”) encr yption. Unlike MS-CHAP version 1, 
which suppor ts one-way authentication, MS-CHAP version 2 suppor ts mutual authentication between connected 
gateways 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 gateway 
you are connecting to does not suppor t MS-CHAP-V2, it will fall back to MS-CHAP-V1, or, if the gateway 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 Password (the CHAP and MS-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 Password, 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 or may be scheduled using the scheduled connections feature. See 
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 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. If you configure your 
Router to initiate PPTP tunnel connections by toggling Initiate Connections to Yes, the Optional Windows 
NT Domain Name field appears. Enter the domain name your network administrator has supplied.
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.
