STEP 1: Connect CyBlock Appliance.
• Connect the appliance to your LAN (local area network) as if it were another
computer.
• Connect the NIC4 LAN port on the appliance to a network Hub using an
Ethernet cable.
STEP 2: Connect your computer to the appliance.
This step is similar to configuring a single computer to your network. You will need to
configure:
• IP address
• DNS
• Default gateway
Configure your computer. Record your current IP address information BEFORE making
the changes below, as you will want to change them back after you have successfully
configured the appliance.
• From the Start menu on your computer, open Settings and click Network &
Internet and then Network and Sharing Center.
• Under View your active networks, click Local Area Connection.
• The Local Area Connection Status screen (Figure 1) will appear. Click the
Properties button.
• Select Internet Protocol (TCP/IP) (Figure 2), and then click the Properties
button.
• Select Use the following IP address (Figure 3).
• In the IP address field, type “10.40.10.2.”
• In the Subnet mask field, type “255.255.255.0.”
• Click OK, and then restart your computer.
Connect to the appliance browser interface. When your computer comes back up, open a
browser. In the address bar, type “http://10.40.10.3” and press ENTER. You can now
access the appliance through this interface (Figure 4). Enter the following information
to log on:
• Logon: admin
• Password: password

STEP 3: Configure the appliance.
Now that you have logged on to the CyBlock Appliance browser interface, go to the
Settings - Network - Configuration screen (Figure 5).
• In the Host Name field, enter a “friendly” name for the appliance.
• Next, enter an IP address that fits into your network IP scheme for CyBlock
Appliance.
• Enter the subnet mask.
• Enter the default gateway IP address of your network.
• In the DNS Domain field, enter the DNS domain name (including suffix).
• In the DNS 1 field, enter the IP address of your primary DNS server.
• If you have a secondary DNS server, enter that IP in the DNS 2 field and so
forth.
• Click Submit to apply the configuration.
STEP 4: Configure your computer back to its original IP scheme.
Using the IP information you recorded before making the changes to connect to the
appliance, change your computer back to its original IP scheme using the instructions
in STEP 2.
STEP 5: Put the appliance into production.
The appliance can be put into production in the following ways:
Bridge Mode
In Bridge mode, the appliance works as an inline device between your network and the
Internet. It acts like a bridge, allowing Internet traffic to flow transparently through it.
You want to place CyBlock Appliance in front of all computers that you want to filter
and behind your firewall/cable modem. Using an Ethernet cable, plug your filtered
internal network traffic (LAN) into the NIC4 port. Next, plug your unfiltered traffic
(WAN) into the NIC3 port.

Proxy Mode
In Proxy mode, traffic is sent to CyBlock Appliance as proxy requests. CyBlock
Appliance then determines if the request should be blocked or allowed based on your
filtering policies. Connect the appliance similar to your computer. Using an Ethernet
cable, plug the NIC4 LAN port on the appliance into a network Hub.

For more information and technical specifications, see our CyBlock Appliance
Datasheet.
What’s Next?
The CyBlock Appliance client software can be installed for protocol authentication,
which can be done centrally. By default, the appliance allows for local reporting,
but you have the option to install and configure Cyfin for remote reporting. These
instructions are located in the product manual. Access the product manual from the
CyBlock Appliance interface by going to Help - User Guide.
