Filtering Client. (For Remote Filtering Client installation instructions, see
Remote Filtering Client, page 131.)
The Remote Filtering Server should be installed on a separate, dedicated
machine. This machine must be able to communicate with the Websense
Filtering Service and with the remote workstations outside the network
firewall. The Remote Filtering Server machine does not have to be joined to a
domain.
The Remote Filtering Server should be installed inside your organization’s
outermost network firewall, but in the DMZ outside the firewall that protects
the rest of the corporate network. For more information about deploying the
Remote Filtering Server in your network, see the Remote Filtering section in
the Deployment Guide for Websense Enterprise and Web Security Suite.
To provide failover capability for the primary Remote Filtering Server, you
can install secondary and tertiary Remote Filtering Servers. Each Remote
Filtering Client can be configured to connect with a primary, secondary, and
tertiary Remote Filtering Server. If the primary server is unavailable, the
client attempts to connect with the secondary, then the tertiary, then the
primary again, and so on.
Note
To enable the Remote Filtering components, you must
subscribe to the remote filtering service.
Important
 Install only one primary Remote Filtering Server for
each Filtering Service in your network.
 Do not install the Remote Filtering Server on the same
machine as the Filtering Service or Network Agent.
 Remote Filtering Server is supported on Windows
Server
®
2003 only if Service Pack 1 has been
installed.
 Do not enable DHCP on the Remote Filtering Server
machine.
