https://campus.barracuda.com/doc/8650776/

To establish wireless Internet connections, you can install the external Barracuda 3G USB modem on

the Barracuda NextGen Firewall X-Series. 3G connections are ideal for backup lines and for use in

mobile oﬃces or locations without terrestrial Internet links.

After you connect the Barracuda USB modem to the X-Series Firewall, conﬁgure the provider settings.

Then verify that the default network route and network interface of the 3G WAN link have been

successfully introduced and are available.

Step 1. Connect the Barracuda 3G modem

To connect the Barracuda modem:

Follow the steps in the Barracuda 3G Modem Quick Start Guide to insert the SIM card into

the Barracuda USB modem.

Connect the Barracuda modem to an empty USB port of the X-Series Firewall.

Connect the antenna to the Barracuda modem and place it in a stable location.

Restart your ﬁrewall so that it recognizes the Barracuda modem.

Go to the BASIC > Administration page.

In the System Reload/Shutdown section, click Restart.

Step 2. Conﬁgure the provider settings

Go to the NETWORK > IP Conﬁguration page.

In the 3G Network Interface section, select the following settings:

Enable 3G Network Interface: Yes

Classiﬁcation: WAN

Conﬁgure the remaining 3G Network Interface settings for your network requirements.

You can conﬁgure the Barracuda modem to automatically choose the transmission

standard with the best transmission performance. For Radio Preference, click Auto.

For the initial conﬁguration, keep the default Metric value of 400. In a multiprovider

conﬁguration, the ﬁrewall chooses the interface with the lowest metric for outgoing traﬃc.

If authentication is required, enter the username and password for establishing a

connection to your ISP. If authentication is not required, select the No Auth check box.

If a pin number is required to unlock your SIM card, enter it in the SIM PIN ﬁeld.

To use the DNS server that is assigned by your ISP, set Use Assigned DNS to Yes. The

ﬁrewall then uses the DNS servers of the ISP for DNS requests.

To make the ﬁrewall reachable with a unique identiﬁer (DNS-resolvable name), set Use
