Important  If you are using Content Gateway on a V-Series appliance, Content Gateway is installed when the appliance is factory imaged and upgraded with the appliance patch facility.

CPU	Quad-core running at 2.8 GHz or faster
Memory	6 GB minimum; 8 GB recommended
Disk space	2 disks: 100 GB for the operating system, Websense Content Gateway, and temporary data.
	147 GB for caching If caching will not be used, this disk is not required. The caching disk: Should have minimum size of 2 GB, maximum 147 GB for optimal performance Must be a raw disk, not a mounted file system Must be dedicated Must not be part of a software RAID Should be, for best performance, a 10K RPM SAS disk on a controller that has at least 64MB of write-through cache
Network Interfaces	2: If not installed on an appliance, policy engine will fail to do auto-registration if there is no eth0 on the box.

Router

Must support WCCP v2, or Policy Based Routing (PBR). A Cisco router must run IOS 12.2 or later. Client machines, the destination Web server, and Websense Content Gateway must reside on different subnets.

—or— Layer 4 switch

You may use a Layer 4 switch rather than a router. To support WCCP, a Cisco switch requires the EMI or IP services image of the 12.2SE IOS release (or later). To support L2 forward or return, Content Gateway must be Layer 2 adjacent to the switch. The switch must be able to rewrite the destination MAC address of frames traversing the switch. The switch must be able to match traffic based on the layer 4 protocol port (i.e., TCP port 80).

Important  You can update packages on your Red Hat Enterprise Linux installations and patch kernels if the underlying kernel upgrade does not change the kernel ABI.

Important  Content Gateway is designed to run on a dedicated machine and is not guaranteed to be compatible with other server applications installed on the same machine.

Important  Web Security Policy Server and Filtering Service must be installed before Content Gateway.

Note  Browser restrictions apply only to the use of the Content Gateway manager and not to client browsers proxied by Content Gateway.

Note  If Content Gateway is running on a V-Series appliance, it is installed during factory imaging and upgraded when the v7.8.2 patch is applied. You do not need to download the installer.
