Network Agent is a software component used to provide security for protocols other than HTTP and HTTPS. It provides bandwidth optimization data and enhanced logging detail.
Network Agent continually monitors overall network usage, including bytes transferred over the network. The agent sends usage summaries to other Websense software at predefined intervals.
Network Agent is typically configured to see both inbound and outbound traffic in your network. The agent distinguishes between:
*
Requests sent from internal machines to internal machines (hits to an intranet server, for example)
*
Requests sent from internal machines to external machines such as web servers (user Internet requests, for example)
You choose whether blocking information for non-HTTP protocols is routed through interface C or interface N.
Guidelines for configuring network interface N
 
Select an interface to use to send blocking information for non-HTTP and HTTPS traffic
*
Select Interface C only if you want to use interface C to send blocking information.
*
Select Interface N if network interface N is connected to a bidirectional span port, and you want to use N to transport blocking information.
Blocking NIC settings configured in Web Security manager do not override the settings you enter in this pane. The settings in Appliance manager take precedence.
IP address of interface N
Required.
Network Agent should be able to see the outbound and inbound traffic in your network. Network Agent ignores ports 80, 443, 8070, and 8080.
Subnet mask
Required if interface N is selected. Otherwise the subnet mask has a fixed value of 255.255.255.255.
Default gateway
Required if Interface N is checked. Otherwise, the field is disabled.
Primary DNS
Required.
IP address of the domain name server.
Secondary DNS
Optional.
Serves as a backup in case the primary DNS is unavailable.
Tertiary DNS
Optional.
Serves as a backup in case the primary and secondary DNSes are unavailable.
Network Agent can instead be installed on a different server in the network.
