Barracuda Networks Link Balance Quick Start Manual

The Barracuda Link Balancer routes and manages traffic across multiple Internet
connections. It optimizes the use of multiple Internet links, such as T1s, T3s, DSL and
cable connections from one or more Internet service providers. The Barracuda Link
Balancer:
•
aggregates Internet connection links
•
provides automated failover in case of link failure
•
manages bandwidth
•
performs Quality of Service (QoS) for Internet applications
•
includes DHCP server and DNS caching server
•
acts as a traditional firewall
This guide describes how to deploy the Barracuda Link Balancer as the default gateway
for your network. In this configuration, the Barracuda Link Balancer sits between the
Internet and your switch, acting as both firewall and router, and replacing your existing
firewall or router. Other deployment configurations are described in the Barracuda Link
Balancer Administrator's Guide.
The instructions given here provide a method to configure the Barracuda Link Balancer
completely before connecting it to the Internet. We recommend reading these steps fully
before starting the setup.

•

If you already have a firewall, retrieve the settings so that they can be configured
in the Barracuda Link Balancer. Record the IP Address and type of link for each
Internet connection.
