This communication is authenticated and encrypted.When installing Remote Filtering:The Remote Filtering Server should be installed on a dedicated machine that cancommunicate with the Filtering Service machine. See Table 8, on page 42.Do not install Remote Filtering Server on the same machine as the FilteringService or Network Agent.Each Filtering Service instance has one Remote Filtering Server.As a best practice, the Remote Filtering Server should be installed inside theoutermost firewall, in the DMZ outside the firewall protecting the rest of thecorporate network. This is highly recommended.See Table 3, on page 18, for operating system requirements for the RemoteFiltering Server.Remote Filtering Client system recommendations:Pentium 4 or greaterFree disk space: 25 MB for installation; 15 MB to run the application512 MB RAMTable 8 Remote Filtering Server System RecommendationsNetwork SizeHardware Recommendations1-500 clients Windows or Linux500-2000 clients Windows or Linux2000-5000 clients Windows or Linux• Quad-Core Intel Xeon processor, 2.5 GHz or greater• 1GB RAM• 20 GB free disk space• Quad-Core Intel Xeon processor, 3.2 GHz or greater• 2GB RAM• 20 GB free disk space• Quad-Core Intel Xeon processor, 3.2 GHz or greater• 2GB RAM• 20 GB free disk space42 Websense Web Security and Websense Web Filter
