Check Enable to enable the web cache.
Selecting a cache size
Select the amount of memory (RAM) on the CyberGuard SG appliance to be reserved for
caching Internet objects. The maximum amount of memory you can safely reserve
depends on what other services the CyberGuard SG appliance has running, such as
VPN or a DHCP server.
If you are using a Network Share (recommended, see below), it is generally best to set
this to 8 Megabytes.
If you are unable to use a Network Share, start with a small cache (8 Megabytes or 16
Megabytes) and gradually increase it until you find a safe upper limit where the
CyberGuard SG appliance can still operate reliably.
Setting up a network share
Typically, the CyberGuard SG appliance’s web cache is most useful when utilizing a
Network Share for additional storage space. The CyberGuard SG appliance is not
equipped with a hard disk of its own, so is quite limited in terms of the amount of Internet
objects it can cache.
A network share is a shared folder or drive on a local Windows PC, or a PC running
another operating system capable of SMB sharing (such as a Linux PC running the
SAMBA service).
