10-6 Firmware Version 4.6 Addendum
■ 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. See “Scheduled Connections” in the User’s Reference Guide.
■ 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.
■ 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.
Note: A peculiarity associated with VPNs is that when a PAC has NAT applied to a Connection Profile set for
PPTP data link encapsulation, the PNS and devices behind it, cannot Ping the PAC’s tunnel end-point IP
address. This is because ICMP packets have no port association, and thus will be discarded rather than being
processed by NAT.
