Web Proxy Server that communicates with Filtering Service. The Sun

Web Proxy Plug-in is supported only on Solaris.

 Remote Filtering components

The Remote Filtering components are required only if you need to enable

web filtering on user workstations located outside your organization’s

network firewall or internet gateway. They can be installed from a

Custom installation only.

 Remote Filtering Server: Should be installed on a separate,

dedicated machine. This machine must be able to communicate with

the Filtering Service and with Remote Filtering Clients on user

workstations that may be used both inside and outside the network

firewall. The Remote Filtering Server installs on Windows, Linux,

and Solaris.

The Remote Filtering Server automatically detects whether clients are

inside or outside of the network firewall. If it determines that a client

is inside the firewall, the user is filtered just like other internal clients.

Remote Filtering is only activated if the client is outside the firewall.

To provide failover protection for the primary Remote Filtering

Server, you can install secondary and tertiary Remote Filtering Servers.

If a Remote Filtering Client on a remote workstation cannot connect

with the primary Remote Filtering Server, it will try to connect with

the secondary, then the tertiary, then the primary again, and so on.

• 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.

• The Remote Filtering Server machine does not have to be joined

to a domain.

Remote Filtering components are not included in the deployment

diagrams provided in this chapter. For deployment information and

network diagrams, see the Remote Filtering section in the

Deployment Guide for Websense Enterprise and Web Security Suite.

Note

To enable the Remote Filtering components, you must

subscribe to the remote filtering service.
