Deploying Network AgentFor information on configuring multiple NICs, consult the Websense Manager Help.Figure 12 Dual NIC configurationNAT and Network Agent deploymentIf you use Network Address Translation (NAT) on internal routers, Network Agentmay be unable to identify the source IP address of client machines. When NetworkAgent detects traffic after being passed through such a router, the agent sees the IPaddress of the router’s external interface as the source of the request, rather than the IPaddress of the client machine.To address this issue, either disable NAT, or install Network Agent on a machinelocated between the NAT router and the monitored clients.62 Websense Web Security and Websense Web Filter
