SonicWALL UTM appliances with a USB extension port can support either an external 3G interface or analog modem interface. When the appliance does not detect an external interface, a 3G/Modem tab is displayed in the left-side navigation bar.
By default, the SonicWALL UTM appliance will attempt to auto-detect whether a connected external device is a 3G interface or an analog modem interface. You can manually specify which type of interface you want to configure on the 3G/Modem > Settings page.
The 3G/Modem Device Type pulldown menu provides the following options:
|
•
|
Auto-detect
- The appliance attempts to determine if the device is a 3G or analog modem.

for information on configuring an analog modem.
