• P1 only enabled. When only P1 is enabled, connect it to the network for both incoming
and outgoing traffic.
• P1 and P2 enabled. When both P1 and P2 are enabled, you must connect P1 to the
internal network and P2 toward the Internet.
Note — You can only enable and configure the P1 interface for data traffic in the System
Setup Wizard. If you want to enable the P2 interface, you must do so after system setup in the
web interface or using the
Setup Wizard. If you want to enable the P2 interface, you must do so after system setup in the
web interface or using the
ifconfig
command. For more information about configuring the
P2 interface, see “Configuring Network Interfaces” on page 485.
How you physically connect the data interfaces to the network depends on how you deploy
the appliance. For more information, see “Deploying the Web Proxy in Explicit Forward
Mode” on page 33 and “Deploying the Web Proxy in Transparent Mode” on page 34.

L4 Traffic Monitor Interfaces
The appliance uses the T1 and T2 interfaces for listening to traffic on all TCP ports. You can
connect just T1 or both T1 and T2 using an Ethernet cable, depending on whether you use
simplex or duplex communication.

Example Deployment
Figure 3-2 on page 32 shows a sample deployment scenario with both the Web Proxy and L4
Traffic Monitor enabled. In this example, the Web Proxy is deployed in transparent mode and
only the P1 port is connected to either a L4 switch or a WCCP router.
