The Modem > Advanced page is used to configure the Remotely Triggered Dial-Out feature, which enables network administrators to remotely initiate a WAN modem connection from a SonicWALL UTM appliance.
The following process describes how a Remotely Triggered Dial-Out call functions:
|
1.
|
|
2.
|
If the SonicWALL is configured to authenticate the incoming call, it prompts the network
administrator to enter a password. Once the call is authenticated, the SonicWALL terminates the call.
|
|
Note
|
After three incorrect password attempts, the SonicWALL terminates a Remotely Triggered
Dial-out authentication session. Each password attempt is allowed a maximum of 60 seconds. If a dial-out session is terminated, the SonicWALL can be called again for another Remotely Triggered Dial-out authentication session.
|
|
3.
|
The SonicWALL then initiates a modem connection to its dial-up ISP, based on the
configured dial profile.
|
|
4.
|
|
Note
|
If LAN- to-WAN traffic on the SonicWALL generates a dial-out request at the same time as
a Remotely Triggered Dial-out session is being authenticated, the Remotely Triggered Dial-out session is terminated and the SonicWALL initiates its own dial-out session.
|
Before configuring the Remotely Triggered Dial-Out feature, ensure that your configuration meets the following prerequisites:
|
•
|
The dial profile is configured for
dial-on-data
.
|
|
•
|
The SonicWALL Security Appliance is configured to be managed using HTTPS, so that the
device can be accessed remotely.
|
|
•
|
Enter a value in the
Enable Max Connection Time (minutes)
field. If you do not enter a value in this field, dial-out calls will remain connected indefinitely, and you will have to manually terminate sessions by clicking the Disconnect
button.
|
To configure Remotely Triggered Dial-Out, go the Modem > Advanced screen.
|
1.
|
Check the
Enable Remotely Triggered Dial-out
checkbox.
|
|
2.
|
(Optional) To authenticate the remote call, check the
Requires authentication
checkbox and enter the password in the Password:
and Confirm Password:
fields.
|
The Bandwidth Management section allows the administrator to enable egress (outbound) or ingress (inbound) bandwidth management services on the modem interface.
|
Note
|
Bandwidth management is a service and must be registered. To configure the service,
navigate to the Application Firewall
section of the user interface.
|
|
1.
|
Click the
Enable Egress Bandwidth Management
checkbox to enable bandwidth management policy enforcement on outbound traffic.
|
|
2.
|
Click the
Enable Ingress Bandwidth Management
checkbox to enable bandwidth management policy enforcement on inbound traffic.
|
|
3.
|
Select a
Compression Multiplier
from the drop-down list.
|
The Connection Limit section allows the administrator to set a host/node limit on the modem connection. This feature is especially useful for deployments where the modem connection is used as an overflow or in load-balanced situations to avoid over-taxing the connection.
In the Max Hosts field, enter the maximum number of hosts to allow when this interface is connected. The default value is “0”, which allows an unlimited number of nodes.
