Chapter 5: Initial Setup

Configuring Network Agent to use Multiple NICs

Each Network Agent instance must use at least one designated NIC. However,

Network Agent is capable of using multiple NICs. If you installed Network

Agent on a machine with multiple NICs, you can configure it to use different

NICs for different purposes. For example, you can configure Network Agent

to use one NIC for monitoring traffic, and another to send blocking

information to Filtering Service.

To configure Network Agent to use additional NICs, follow the instructions in

the Network Agent chapter in the Administrator’s Guide for Websense

Enterprise and Web Security Suite.

Testing Visibility of Internet Traffic to Network Agent

If you installed Network Agent and have any doubt about its ability to

monitor internet requests from the desired network and to see the replies, you

can conduct a traffic visibility test on the Network Agent machine using the

Websense Traffic Visibility Tool.

Running the Websense Traffic Visibility Tool

Run the Websense Traffic Visibility Tool on the Network Agent machine to

test internet traffic visibility. The NIC that Network Agent is configured to

use must be able to monitor 2-way employee internet traffic for Network

Agent to function properly.

1. To start the tool:

 Windows: From the Start menu, choose Programs (or All

Programs) > Websense > Utilities > Traffic Visibility Tool.

 Linux or Solaris: Run ./TrafficVisibility.sh from the

Websense installation directory (

/opt/Websense).

To start a GUI version, run

./TrafficVisibility.sh -g
