Chapter 1 What’s New for FortiOS 5.2.1 : WAN Optimization, Web Cache, and Explicit Proxy : Explicit Proxy Policy Table - for explicit web proxy, explicit FTP proxy and WAN optimization policies
  
Explicit Proxy Policy Table - for explicit web proxy, explicit FTP proxy and WAN optimization policies
Explicit proxy polices now have a dedicated table and creation page, found at Policy & Objects > Policy > Explicit Proxy. The corresponding CLI command is:
config firewall explicit-proxy-policy
You use explicit proxy policies to add policies for the IPv4 and IPv6 explicit web proxy and for the explicit FTP policy. The first step in creating an explicit proxy policy is to select the proxy type (web or FTP). The options available e then depend on the explicit proxy type.
From the CLI you use the explicit web proxy policy to add WAN optimization tunnel policies. In FortiOS 5.0 you added WAN optimization tunnel policies by setting the source interface to wanopt. In FortiOS 5.2 you create an explicit web proxy policy from the CLI and set the proxy type to wanopt. For example:
configure firewall explicit-proxy-policy
edit 0
set proxy wanopt
set dstintf internal
set srcaddr all
set dstaddr server-subnet
set action accept
set schedule always
set service ALL
next
end
