Barracuda Link Balancer - Quick Start Guide
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 Balancer
:
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
http://192.168.200.200:8000
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.
Activate the Barracuda Link Balancer
If you see an activation warning message at the top of every page on the
Barracuda Link Balancer web interface, follow these steps to activate:
1.
Click on the link in the warning message or use the link on the BASIC >
Status page to open up the
Barracuda Networks Product Activation
page in a new browser window.
2. Fill in the required fields and click Activate. A confirmation page opens to
display the terms of your subscription.
On the BASIC > Status page, you may need to enter the activation code
from the Barracuda Networks Product Activation
page for activation
.
Update the Firmware
Go to ADVANCED > Firmware Update. If there is a new Latest General
Release available:
1. Click Download Now and wait until downloading has completed.
2.
Click Apply Now to start the updating process, after which the
unit will
automatically reboot.
Configure Permanent WAN Settings
Configure the permanent settings for the WAN links to be connected to the unit.
Some of the configuration information for the WAN links, such as the upload and
download speed, is provided by your ISP. Be sure to enter these values
correctly.
1. Unplug the Ethernet cable connecting the WAN port to your office network.
2. Go to the BASIC > Links page.
3. For each link that will be connected to this unit:
a. Click the relevant WAN port in the graphic.
b. In the Links Configuration section, enter the details for the link to be
connected to the WAN port and save the changes.
Note: For each WAN interface that has a static IP address, enter the IP
addresses of all of your servers with public IP addresses in the Additional IP
Addresses field. You will need to reconfigure those servers with private IP
addresses. In the next step you can create 1:1 NAT rules to map the public IP
addresses to the private IP addresses of the servers.
Configure the Barracuda Link Balancer Firewall
If the Barracuda Link Balancer replaces your current firewall, create firewall rules
on the Barracuda Link Balancer to match the settings of your current firewall:
1. Go to the FIREWALL > NAT page to add 1:1 NAT and port forwarding
rules.
2. Respective inbound and oubound rules are automatically created. However,
if necessary, go to FIREWALL > Access Rules to create any additional
inbound and outbound rules.
