Chapter 2: Installing the Barracuda Link Balancer 15
You do not need to update your existing firewall configuration unless you want to make it aware of
the new WAN link(s). To do so:
1. Add firewall rules so that traffic from the new links is handled correctly.
2. If you want to be able to manage your existing firewall remotely, add an alias on your firewall
for the other links in case the first link is unavailable.
Your Barracuda Link Balancer should be ready for operation. There are a number of other
configuration options available. Please refer to the next chapter, Configuring the Barracuda Link
Balancer on page 19, to review these options.
Replacing Your Firewall Installation
These instructions describe how to deploy the Barracuda Link Balancer as the default gateway for
your network, replacing your existing firewall or router.
The steps documented here provide a method to configure the Barracuda Link Balancer completely
before connecting it to your production system. This method allows you to copy the firewall
configuration of your existing firewall to the Barracuda Link Balancer. A similar process is described
in the Barracuda Link Balancer Quick Start Guide
Step 1: Prepare for the Installation
Before installing your Barracuda Link Balancer, verify you have the necessary equipment:
• Barracuda Link Balancer, AC power cord (included)
• Ethernet cables
• a PC with a Web browser
Plug in the Barracuda Link Balancer and power it on.
Step 2: Activate the Barracuda Link Balancer with Temporary Network
Settings
Follow these steps to configure the Barracuda Link Balancer with temporary settings and activate it:
1. Change the network settings of a PC with a Web browser installed to use an IP address of
192.168.200.10, subnet mask of 255.255.255.0 and gateway of 192.168.200.200. Depending on
the model, there may be a LAN port on the front of the Barracuda Link Balancer. If there is,
connect an Ethernet cable from the PC to that LAN port.
