■Name — Identifies the tunnel. Clicking the name of a connection displays the Edit VPN Connection screen. See “Adding and Editing VPN Connections” below.

■Description — A text description that enables you to identify a connection. This field in the table additionally displays whether the connection is currently active.

■Type — Indicates the type of connection.

■Enabled — This check box allows you to enable or disable a connection without deleting it and thus losing the connection details. Check this box to enable a connection. Clear this box to disable the connection. If the connection is active it will be disconnected.

Additionally there are three buttons outside the table:

■Help — displays the online help page for this screen.

■Refresh — updates the contents of the window allowing you to see the current status of connections.

■New — creates a new VPN connection. See “Adding and Editing VPN Connections” below.

Adding and Editing VPN Connections

This screen allows you to add new IPSec, L2TP over IPSec and PPTP connections and to edit existing ones. When adding or amending values on this screen remember that both sides of an IPSec, L2TP over IPSec or PPTP connection must contain the same information.

An IPSec, L2TP over IPSec or PPTP connection cannot therefore be activated until both ends of the tunnel have been configured.

■Connection Name/User Name — the ID of the remote gateway (the value entered in This Gateway’s ID on the remote gateway or the remote user’s login name). This can be a name (containing numbers and letters but no punctuation) or an IP address but cannot be a domain name.

If the Connection Name is set using numeric IP addresses then the Gateway to Gateway connection will use main mode. Otherwise it will use aggressive mode.

■Description — a description of the connection. This can be different on each Gateway as it is not used in the connection.

■Connection Type — choose either Gateway to Gateway (only available with IPSec) to connect to another Gateway or Remote User Access to create a connection for a remote computer.

If the remote site has another gateway with an established IPSec, L2TP over IPSec or PPTP connection then there is no need to create a connection for a remote user on that site.

If you configure an IPSec connection for a remote computer then that computer will require software that supports IPSec. If you configure an L2TP over IPSec or PPTP connection for a remote computer then you should contact Microsoft for information on whether an upgrade is required.

■Tunnel Type — Choose either IPSec (either Remote User Access or Gateway to Gateway), L2TP over IPSec or PPTP.
