specified in the VPN Feature Chart may connect at the same time without affecting the
performance of the SonicWALL.
The VPN Interface
Click VPN on the left-side of the SonicWALL management station interface. There are
four tabs in the VPN interface:
•
Summary
•
Configure
•
RADIUS
•
Certificates
The Summary tab has two sections: the Global IPSec Settings, and the Current
IPSec Security Associations.
Global IPSec Settings
The Global IPSec Settings section displays the Unique Firewall Identifier which
defaults to the serial number of the SonicWALL appliance. You may change the
Identifier, but the default value should be used for configuring VPN tunnels. The
Enable VPN check box must be checked to allow VPN security associations. The
Disable all VPN Windows Networking (NetBIOS) broadcast check box is also
checked. This check box disables NetBIOS broadcasts for every Security Association
configuration. The Enable Fragmented Packet Handling check box should be
checked if the VPN log report shows the log message "Fragmented IPSec packet
dropped". Leave it unchecked until the VPN tunnel is established and in operation.
Current IPSec Security Associations
This section displays all of the VPN configurations in the SonicWALL appliance. If you
click on the name of the security association, the security association settings are
displayed. Alternatively, click on the Notepad icon to edit a VPN configuration. You
may also delete a configuration by clicking on the Trashcan icon.
Also, you can view the number of Security Associations enabled, the number of SAs
defined, and the number of SAs allowed. Each Security Association configured is listed
in this section. An asterisk appears next to a Security Association that is disabled.
