Modem > Advanced

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.

Remotely Triggered Dial-Out

The following process describes how a Remotely Triggered Dial-Out call functions:

1. The network administrator initiates a modem connection to the SonicWALL located at the remote office.
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. The network administrator accesses the SonicWALL web management interface to perform the required tasks.

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.

Configuring Remotely Triggered Dial-Out

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.

Bandwidth Management

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.

Connection Limit

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.
