Internet service groups in policies

This feature provides support for Internet Service Groups in traffic shaping and firewall policies. Service groups can be used as the source and destination of the policy. Internet Service Groups are used as criteria to match traffic; the shaper will be applied when the traffic matches.

To use a group as a destination, internet-service must be enabled. To use a group as a source, internet-service-src must be enabled.

The following CLI variables are available in the firewall policy and firewall shaping-policy commands:

Variable	Description
internet-service-group <string>	Internet Service group name.
internet-service-custom-group <string>	Custom Internet Service group name.
internet-service-src-group <string>	Internet Service source group name.
internet-service-src-custom-group <string>	Custom Internet Service source group name.

Examples

The following examples use the below topology.

Example 1

In this example, the PC is allowed to access Google, so all Google services are put into an Internet Service Group.

To configure access to Google services using an Internet Service Group using the CLI:

1. Create a Service Group:

   config firewall internet-service-group
       edit "Google_Group"
           set direction destination
           set member 65537 65538 65539 65540 65542 65543 65544 65545 65550 65536 65646
       next
   end

2. Create a firewall policy to allow access to all Google Services from the PC:

   config firewall policy
       edit 1
           set name "PC to Google"
           set srcintf "port2"
           set dstintf "port1"
           set srcaddr "PC"
           set internet-service enable
           set internet-service-group "Google_Group"
           set action accept
           set schedule "always"
           set fsso disable
           set nat enable
       next
   end

To configure access to Google services using an Internet Service Group in the GUI:

1. On the FortiGate, create a Service Group using the CLI.
2. Go to Policy & Objects > Firewall Policy, and create a new policy.
3. Set the Destination as the just created Internet Service Group.

   

4. Configure the remaining options as shown, then click OK.

   On the policy page, hover over the group to view a list of its members.

   

Example 2

In this example, two office FTP servers are put into an Internet Custom Service Group, and the PC connection to the FTP servers is limited to 1Mbps.

To put two FTP servers into a custom service group and limit the PC connection speed to them using the CLI:

1. Create custom internet services for the internal FTP servers:

   config firewall internet-service-custom
       edit "FTP_PM"
           config entry
               edit 1
                   config port-range
                       edit 1
                           set start-port 21
                           set end-port 21
                       next
                   end
                   set dst "PM_Server"
               next
           end
       next
       edit "FTP_QA"
           config entry
               edit 1
                   config port-range
                       edit 1
                           set start-port 21
                           set end-port 21
                       next
                   end
                   set dst "QA_Server"
               next
           end
       next
   end

2. Create a custom internet server group and add the just created custom internet services to it:

   config firewall internet-service-custom-group
       edit "Internal_FTP"
           set member "FTP_QA" "FTP_PM"
       next
   end

3. Create a traffic shaper to limit the maximum bandwidth:

   config firewall shaper traffic-shaper
       edit "Internal_FTP_Limit_1Mbps"
           set guaranteed-bandwidth 500
           set maximum-bandwidth 1000
           set priority medium
       next
   end

4. Create a firewall shaping policy to limit the speed from the PC to the internal FTP servers:

   config firewall shaping-policy
       edit 1
           set name "For Internal FTP"
           set internet-service enable
           set internet-service-custom-group "Internal_FTP"
           set dstintf "port1"
           set traffic-shaper "Internal_FTP_Limit_1Mbps"
           set traffic-shaper-reverse "Internal_FTP_Limit_1Mbps"
           set srcaddr "PC"
       next
   end

To put two FTP servers into a custom service group and limit the PC connection speed to the using the GUI:

1. Create custom internet services for the internal FTP servers using the CLI.
2. Create a custom internet server group and add the just created custom internet services to it using the CLI.
3. Create a traffic shaper to limit the maximum bandwidth:
   1. Go to Policy & Objects > Traffic Shapers, and click Create New.
   2. Enter a Name for the shaper, such as Internal_FTP_Limit_1Mbps.
   3. Set the Traffic Priority to Medium.
   4. Enable Max Bandwidth and set it to 1000.
   5. Enable Guaranteed Bandwidth and set it to 500.
   6. Click OK.
4. Create a firewall shaping policy to limit the speed from the PC to the internal FTP servers:
   1. Go to Policy & Objects > Traffic Shaping Policy, and click Create New.
   2. Set the Destination as the just created Custom Internet Service Group, and apply the just create traffic shaper.

      

   3. Configure the remaining options as shown, then click OK.
