• Web proxy in transparent mode. If you want to use one proxy port for all traffic, connect 

port P1 to an L4 switch or a WCCP router using an Ethernet cable. If you want to use two 
proxy ports for traffic, connect port P2 to an L4 switch or a WCCP router using an Ethernet 
cable, and connect port P1 to the internal network. 

For more information about deploying the Web Proxy in transparent mode, see 
“Deploying the Web Proxy in Transparent Mode” on page 34.

Note — When you configure the proxy in transparent mode and connect it to a WCCP 
router, you must configure the appliance after you run the System Setup Wizard to create 
at least one WCCP service. For more information about creating WCCP services, see 
“Adding and Editing a WCCP Service” on page 478.

• Web proxy in explicit forward mode. If you want to use one proxy port for all traffic, 

connect port P1 to a network switch using an Ethernet cable. If you want to use two proxy 
ports for traffic, connect port P2 to a network switch using an Ethernet cable, and connect 
port P1 to the internal network. 

For more information about deploying the Web Proxy in explicit forward mode, see 
“Deploying the Web Proxy in Explicit Forward Mode” on page 33.

• L4 Traffic Monitor. Connect the Traffic Monitor ports to the Ethernet tap according to the 

tap communication type:

• Ethernet tap using simplex. Connect port T1 to the Ethernet tap so it receives all 

outgoing traffic (from the clients to the Internet), and connect port T2 to the Ethernet 
tap so it receives all incoming traffic (from the Internet to the clients).

• Ethernet tap using duplex. Connect port T1 to the Ethernet tap so it receives all 

incoming and outgoing traffic.

For more information about deploying the L4 Traffic Monitor, see “Deploying the L4 
Traffic Monitor” on page 41.

Once you know how you will install the appliance in your network, you can gather the 
necessary information, such as IP addresses, to enter in the System Setup Wizard. You can use 
the worksheet in Table 4-1 to write down the configuration options you decide on. Then, 
when you run the System Setup Wizard, you can use the information you enter in the 
worksheet to configure the initial setup.
