WAN optimization and web
caching
You can use FortiGate WAN optimization and web caching to improve performance and
security of traffic passing between locations on your wide area network (WAN) or from the
Internet to your web servers. This section introduces FortiGate WAN optimization and web
caching and describes how to configure these features.
For a more complete description of FortiGate WAN optimization, web caching see the
FortiGate WAN Optimization, Web Cache, and Web Proxy User Guide.
If you enable virtual domains (VDOMs) on the FortiGate unit, WAN optimization is
available separately for each virtual domain. For details, see “Using virtual domains” on
page 159.
This section contains the following topics:
• Configuring WAN optimization
• Configuring a WAN optimization rule
• Configuring WAN optimization peers
• Configuring authentication groups
• WAN optimization monitoring
• Changing web cache settings
Configuring WAN optimization
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. For more
information about enabling virtual domains, see “Enabling VDOMs” on page 164.
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 “Moving a rule
to a different position in the rule list” on page 685.
To view the WAN optimization rule list, go to WAN Opt. & Cache > Rule.
Before you add WAN optimization rules, you must add firewall policies to accept the traffic
that you want to optimize. 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.
