Starting and stopping a
VPN client connection
Two start mechanisms are defined:
 Manual Dialup
 Automatic Start.
When you use pre-shared key authentication, both start mechanisms require a
number of parameters to be set. The set of parameters depends on which Server
Vendor you selected.
Selecting the Manual Dialup method, no further parameters have to be configured.
You have to dial in to the VPN server each time you need the secure connection.
Whenever you dial in, you have to enter a set of parameters to join the VPN.
Select the Automatic Start method when multiple terminals in your LAN have
access to the secure connection, and individual users do not need to authenticate.
The set of parameters required to access the VPN server are stored in the
SpeedTouch™ configuration. Furthermore. you specify the range of local terminals
that may access the secure VPN connection. Once configured, the automatic start
procedure provides permanent access to the secure connection for the authorized
terminals, without further user interaction.
