Quick Start for Network AgentActivities and Communication: Which NIC is used to activate Websense blocking? By default,the NIC you are editing is used. Do not use a NIC without a valid IP address for blocking.• Filter and log HTTP requests: (Active by default in Stand-alone Mode) Network Agentperforms full HTTP monitoring and logging using the selected NIC.• Log HTTP requests: Network Agent logs but does not filter HTTP requests. Use this if theintegration product filters HTTP traffic, but you want to use Network Agent’s detailedlogging information for Reporting.• Protocol Management: Should this Network Agent handle non-HTTP protocol andapplication requests via the selected NIC?• If so, check Filter protocol requests not sent over HTTP ports (ProtocolManagement).• Measure bandwidth by protocol (Bandwidth Optimizer) activates the feature.IMPORTANTClick Save Changes above the navigation tree to save the NetworkAgent configuration.Verifying that Network Agent is WorkingRun the Websense Traffic Visibility Tool on the Network Agent machine.1.

Quick Start for Network AgentFieldNetwork CardNetworks TestedIP Address CountIP Address ListDetailDescriptionName of the network interface card (NIC) to test. Active cards on theinstallation machine appear in this list. Cards without an IP address donot appear.Displays the netmasks that are being tested. Use the defaults or addyour own. These netmasks can reside in different network segmentsdepending on the IP address ranges to be filtered.Number of IP addresses for which traffic is detected during the test.Lists all the IP addresses from which internet traffic is being detected.2. From the Network Card drop-down list, select the network interface card (NIC) that theNetwork Agent is configured to use for monitoring.A default list of networks (netmasks) appears. Use the defaults or add your own.3. If the network you want to test does not appear in the default list, click Add Network.• Enter a new netmask value in the Network ID field.The subnet mask defaults to 255.0.0.0 and changes as thenetmask is defined.• Click OK.Your new network appears in the list.4. Select Remove Network to delete a network from the list.5. Click Start Test to begin testing all networks in the list.The counter in the IP Address Count column should begin recording internet trafficimmediately. The counter increments each time the NIC detects an individual IP address from thetarget network in a passing packet. The activity bar at the bottom of the dialog box indicates thata test is underway.If the count for a network remains at zero or is very low, the selected NIC cannot see the traffic itis supposed to monitor.6. If the Network Agent NIC is unable to see the desired traffic:• If the installation machine has multiple NICs, select a different card to test. If this card cansee the desired traffic, configure Network Agent to use this card.• Resolve network configuration issues to make sure that the NIC can see the desired traffic.This might involve connecting to a different router or configuring for port spanning in aswitched environment.7. When you are finished, click Stop Test.8. Click Close.The Network Agent NIC must be able to monitor all assigned internet traffic. If Network Agentcannot see the traffic, either reposition the machine in the network or select another machine forNetwork Agent.Quick Start 15 Network Agent
