Barracuda Networks Link Balancer Quick Start Manual

Thank you for purchasing a Barracuda Link Balancer. This unit routes and manages traffic
across multiple Internet connections and offers many other services. It can be inserted
into your network without any service disruption.
This guide describes how to deploy the Barracuda Link Balancer in your network
replacing your existing firewall (firewall enabled mode). You can also deploy the
Barracuda Link Balancer between the Internet and your already existing firewall (firewall
disabled mode). Instructions for both deployment methods can be found in the Barracuda
Link Balancer Administrator's Guide.
The unit defaults to firewall enabled mode. These instructions allow you to configure the
unit's WAN links and firewall.
Getting Started
To set up your Barracuda Link Balancer, you need the following:

Barracuda Link Balancer, AC Power Cord (included)

Ethernet Cables

PC with Web browser
AC input voltage range is 100-240 volts at 50/60 Hz.
Plug in the Barracuda Link Balancer and power it on.
Prepare the Barracuda Link
1. Set the network settings of a PC to use an IP address of 192.168.200.10,
subnet mask of 255.255.255.0, gateway of 192.168.200.200 and configure
the PC's DNS settings so that the Web browser can display contents from
www.barracudanetworks.com.
2. Connect the PC to the LAN port on the front of the unit using an Ethernet
cable.
3. Access the web interface of the unit by typing
in a web browser. The default username is admin and the default password
is also admin.
4. Go to the BASIC > Links page and click one of the WAN ports in the
graphic. The Type In the Links Configuration section defaults to DHCP
(auto-acquiring an address in the office network) . Alternatively, you may set
it to Static and enter a specific IP address. Click Save Changes.
5. Connect an Ethernet cable from the corresponding WAN port on the front of
the Barracuda Link Balancer to your office network. You should now have
Internet connectivity from your PC.
Note: WAN ports may be labeled WAN 1 / WAN 2 or Port 1 / Port 2.
