Deploying Remote Filtering Server and Client
Deployment and Installation Center | Web Security Solutions | Version 7.7.x
 
Applies to:                                         
*
Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x
With all Web Security solutions, you have the option to use remote filtering software to manage Internet activity for machines that reside or travel outside your network.
*
Remote Filtering Client is installed on each remote machine.
*
The client software communicates with Remote Filtering Server, which acts as a proxy to Websense Filtering Service.
Communication between the components is authenticated and encrypted.
 
* 
Note 
If you have Websense Web Security Gateway Anywhere, you can also use the hybrid service to monitor users outside your network. This does not require software installation on remote machines.
When you install remote filtering components:
*
Install Remote Filtering Server on a dedicated machine that can communicate with the Filtering Service machine.
As a best practice, install Remote Filtering Server in the DMZ outside the firewall protecting the rest of the corporate network. This is strongly recommended.
*
Do not install Remote Filtering Server on the same machine as Filtering Service or Network Agent.
*
Each Filtering Service instance can have only one primary Remote Filtering Server.
Remote Filtering Client system recommendations:
*
Pentium 4 or greater

Free disk space: 25 MB for installation; 15 MB to run the application
