WAN optimization uses these various data storage devices for web caching and byte
caching. All of these options can provide similar web caching and byte caching
performance. If you add more than one storage location (for example, by adding iSCSI to
a FortiGate that already has a FortiGate-ASM-S08 module) you can configure different
storage locations for web caching and byte caching.
If you have not installed a FortiGate-ASM-S08 or ASM-SAS module in a FortiGate unit
with a single-width AMC slot you can still configure and use iSCSI for full WAN
optimization.
A hard disk, the ASM-SAS module, or iSCSI is only required for web caching and byte
caching. All other WAN optimization features, including SSL acceleration, are supported if
the hard disk, SAS, or iSCSI is not available.
You configure iSCSI support from the FortiGate CLI. See the
more information.
The WAN optimization rule list displays WAN optimization rules in their order of matching
precedence.
If virtual domains are enabled on the FortiGate unit, WAN optimization rules are
configured separately for each virtual domain; you must access the VDOM before you can
configure its rules. To access a VDOM, go to System > VDOM, and in the row
corresponding to the VDOM whose policies you want to configure, select Enter.
You can add, delete, edit, and re-order rules in the rule list. WAN optimization rule order
affects rule matching. For details about arranging rules in the rule list, see
affects rule matching" on page 606
on page 607.
To view the WAN optimization rule list, got to WAN Opt. & Cache > Rule.
Before you add WAN optimization rules you must add firewall policies to accept the traffic
to be optimized. Then you add WAN optimization rules that:
• Match WAN traffic to be optimized that is accepted by a firewall policy according to
source and destination addresses and destination port of the traffic
• Add the WAN optimization techniques to be applied to the traffic
