Installation guide

Sun Java System Web Proxy Server  73
Chapter 4: Installing Websense Enterprise or Web Security Suite
you must run the Websense installer and select a Custom installation. For
information, see Installing Websense Components Separately, page 99.
 Network Agent: Network Agent is included as part of a Typical
installation. The machine on which Network Agent is installed must be
deployed so that Network Agent is able to monitor all requests sent from
user workstations to the internet, as well as all replies from the internet to
the requesting workstations. If you install Network Agent on a machine
that cannot monitor the targeted traffic, Network Agent features such as
Protocol Management, Bandwidth Optimizer, and IM Attachment Manager
will not work correctly. For more information about positioning the
Network Agent machine in your network, see the Network Agent chapter
in the Deployment Guide for Websense Enterprise and Web Security Suite.
 Network Interface Card (NIC): The NIC that you designate for use by
Network Agent during installation must support promiscuous mode.
Promiscuous mode allows a NIC to listen to IP addresses other than its
own. (Contact the manufacturer of your card to see if it supports
promiscuous mode.) If the card supports promiscuous mode, it will be set
to that mode by the Websense installer during installation.
After installation, you can run the Traffic Visibility Tool to test whether
the selected NIC can see the appropriate user internet traffic. See Testing
Visibility of Internet Traffic to Network Agent, page 207.
Important
Do not install Network Agent on a machine running any
type of firewall. Network Agent uses a packet-capturing
utility which may not work properly when installed on a
firewall machine. The only exception is a blade server or
appliance that has separate processors or virtual processors
to accommodate Network Agent and the firewall software.
Note
If you install Network Agent on a machine with multiple
NICs, you can configure Network Agent after installation
to use more than one NIC. See Configuring Network Agent
to use Multiple NICs, page 207 for more information.
