Configuring system IP information

The BASIC > IP Configuration page contains the network configuration for your Barracuda Web

Filter. Use this page to change the following settings:

• System IP address and domain configuration

• DNS servers

• Client IP Visibility for HTTP—Specifies whether the Barracuda Web Filter is to expose client

IP Addresses in egress HTTP traffic. If you change this setting to No, all HTTP traffic passing

through the system will have the IP address of the Barracuda Web Filter.

• Static routes

Setting up linked management

Use the ADVANCED > Linked Management page to link multiple Barracuda Web Filters together so

they can synchronize configuration settings. Linked systems can be geographically dispersed and do

not need to be co-located on the same network. Linked management does not provide load-balancing

functionality. The Barracuda Web Filter uses ports 8001 and 8002 to synchronize configuration

between linked systems.

Linked Management is available on the Barracuda Web Filter 410 and above.

Note:

Some network environments may not be suitable to linking multiple Barracuda Web Filter

systems together. For example, if you have multiple network segments that each require different

policies, it may be better to provide a dedicated, unlinked Barracuda Web Filter for each segment. This

way you can configure each Barracuda Web Filter without the configuration settings propagating to

the other systems.

To link two Barracuda Web Filter devices:

1. Complete the installation process for each system as described in Chapter 2 Installation and

Configuration.

2. From the ADVANCED > Task Manager on Barracuda Web Filter 1, verify that no processes are

running. Complete this step for the Barracuda Web Filter 2 as well. No processes should be

running when you link systems together.

3. From the ADVANCED > Linked Management page on Barracuda Web Filter 1, enter the Cluster

Shared Secret password, and click

Save Changes.
