Barracuda Web Filter Release 3.3
24 Chapter 2: Installation and Configuration
Step 10. Test and adjust the Barracuda Web Filter
After connecting your Barracuda Web Filter to the network, verify connectivity. Open your Web
browser from a machine on your network. If you cannot browse the Web, review the installation steps
to make sure your Barracuda Web Filter is properly configured and connected to your corporate
firewall and network switch.
If you can browse the Web without any issues, you are ready to adjust the settings on the Barracuda
Web Filter. The most common adjustment to make is to create filters that determine what traffic and
applications the Barracuda Web Filter blocks and accepts. For more information about the available
filters, refer to Creating block and accept filters on page 36.
Go to the
BLOCK/ACCEPT > IP Block/Exempt page, and use the IP and Port Exemption section to
bypass scanning or filtering for clients or targeted servers. To avoid accidentally specifying a broader
than intended an exemption range, be sure to apply the proper subnet mask.
Connecting the Barracuda Web Filter to your network
To connect the Barracuda Web Filter to your network:
1. Connect the Ethernet cable from your corporate firewall to the WAN port on the front panel of
the Barracuda Web Filter. This step may require disconnecting your internal network switch
from the corporate firewall.
Note:
A crossover cable may be needed if your corporate firewall does not have a switchable
port and therefore cannot switch between RX and TX. Another solution is to place a switch
between the corporate firewall and the Barracuda Web Filter.
Note:
You do not need to configure the WAN port. The Barracuda Web Filter creates an
Ethernet bridge between the WAN and LAN ports.
