Configuring the U0/U1/M0 Interface from Network

Configuring the U0/U1/M0 Interface from Network > Interfaces

To configure the U0/U1/M0 interface from the Network > Interfaces page:

Click the configure icon for the U0/U1/M0 interface.

If the interface will be used in Connect on Data mode, select the categories of traffic that will trigger the interface to automatically connect when the appliance detects those types of traffic.

The following categories are supported:

•

•

•

•

•

•

•

Firmware Update requests

•

Syslog traffic

NOTE: To configure the SonicWall appliance for Connect on Data operation, you must select Connect on Data as the Connection Type for the Connection Profile. See 3G/4G > Connection Profiles for more details.

Select the appropriate Management/User Login options to enable remote management of the SonicWall appliance over the 3G interface.

You can select any of the supported management protocol(s): HTTPS, Ping, SNMP, and/or SSH. You can also select HTTP for management traffic. However, bear in mind that HTTP traffic is less secure than HTTPS.

NOTE: Remote manage the appliance over the U0/U1/M0 interface requires that the 3G provider:

Issues a publicly routable IP address upon connection to the 3G network.

Allows external connection to be initiated on their network.

Please contact your 3G provider to determine if they support these requirements.

Select Add rule to enable redirect from HTTP to HTTPS to have the SonicWall automatically convert HTTP requests to HTTPS requests for added security.

To select the preferred configuration profiles for the interface, click the Profiles tab.

Select the appropriate connection profiles for Primary Profile, Alternate Profile 1, and Alternate Profile 2.

NOTE: The connection profiles must be initially configured on the 3G > Connection Profiles page. See 3G/4G > Connection Profiles for more details.

Click on the Advanced tab.

Check the Enable Remotely Triggered Dial-Out check box to enable network administrators to remotely initiate a WAN modem connection. For more information, see Remotely Triggered Dial-Out Settings.

(Optional) To authenticate the remote call, check the Requires authentication check box and enter the password in the Password and Confirm Password fields.

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.

Click the Enable Egress Bandwidth Management check box to enable bandwidth management policy enforcement on outbound traffic.

Click the Enable Ingress Bandwidth Management check box to enable bandwidth management policy enforcement on inbound traffic.

Select a Compression Multiplier from the drop-down list as necessary to appropriately adjust bandwidth calculations if the dial-up device performs compression.

Select the Enable flow reporting check box to have the data for flows on this interface reported to Flow Reporting and the Real-Time Monitor.

NOTE: In earlier SonicOS releases, the failover behavior for the 3G/Modem interface was configured on the Network > Interfaces page. Now, 3G/Modem failover is configured on the Network > Failover & LB page. See Network > Failover & Load Balancing for more information.
