Application control shaping

Traffic shaping is also possible for specific applications, too. Application control shaping works in conjunction with a Shared Shaper or Per-IP Shaper. You must create a shaper with the bandwidth settings you would like to enforce or edit one of the predefined shapers in the Policy & Objects > Traffic Shapers menu.

Traffic shaping policies allow you to enable these shapers and configure application control options. In the traffic shaping policy, you can set an Application Category, Application, and URL Category. You must also specify which security policies to apply your shaper to by setting the Matching Criteria.You can create a traffic shaping policy in the Policy & Objects > Traffic Shaping Policy section.

For application control shaping to work, application control must be enabled in a security policy, through Policy & Objects > IPv4 Policy or Policy & Objects > IPv6 Policy under Security Profiles.

Also, application control shaping will only affect applications that are set to pass in the Security Profiles > Application Control menu.

For more information on application control, see the FortiOS Chapter 22 – Security Profiles Guide.

set srcaddr all set dstaddr all set service ALL

set application 15832

set app-category 23 <Social.Media>

set url-category 37 <Social Networking> set dstintf wan1 <outgoing interface> set traffic-shaper medium-priority

set reverse-traffic-shaper medium-priority end
