• Optimize CIFS traffic from IP addresses 172.20.120.100 to 172.20.120.200
You can do this by adding three active WAN optimization rules to the client side FortiGate
unit. One for each protocol, with port set to 80 for the HTTP rule, 21 for the FTP rule and
1-65535 for the CIFS rule. Then the rules must be arranged in the WAN optimization rule
list with the HTTP and FTP rules above the CIFS rule because the HTTP and FTP rules
include single port numbers.
