Using Internet Service in policy  : Fortigate

This recipe shows how to apply a predefined Internet Service entry into a policy.
The Internet Service Database is a comprehensive public IP address database that combines IP address range, IP owner, service port number, and IP security credibility. The data comes from the FortiGuard service system. Information is regularly added to this database, for example, geographic location, IP reputation, popularity & DNS, and so on. All this information helps users define Internet security more effectively. You can use the contents of the database as criteria for inclusion or exclusion in a policy.
From FortiOS version 5.6, Internet Service is included in the firewall policy. It can be applied to a policy only as a destination object. From version 6.0, Internet Service can be applied both as source and destination objects in a policy. You can also apply Internet Services to shaping policy.
There are three types of Internet Services you can apply to a firewall policy:
  • Predefined Internet Services
  • Custom Internet Services
  • Extension Internet Services

Sample configuration

To apply a predefined Internet Service entry to a policy using the GUI:
  1. Go to Policy & Objects and create a new policy.
  2. In the Source or Destination field, click +.
  3. In the Select Entries pane, click Internet Service.
  4. Locate and click Google.Gmail.
  5. Configure the other fields and then click OK.
To apply a predefined Internet Service entry to a policy using the CLI:
In the CLI, enable the internet-service first and then use its ID to apply the policy.
This example uses Google Gmail and its ID is 65646. Each Internet Service has a unique ID.
config firewall policy
    edit 9
        set name "Internet Service in Policy"
        set srcintf "wan2"
        set dstintf "wan1"
        set srcaddr "all"
        set internet-service enable
        set internet-service-id 65646
        set action accept
        set schedule "always"
        set utm-status enable
        set av-profile "g-default"
        set ssl-ssh-profile "certificate-inspection"
        set nat enable
    next
end
To diagnose an Internet Service entry using the CLI:
# diagnose internet-service id-summary 65646
Version: 0000600096
Timestamp: 201902111802
Total number of IP ranges: 444727
Number of Groups: 7
Group(0), Singularity(20), Number of IP ranges(142740)
Group(1), Singularity(19), Number of IP ranges(1210)
Group(2), Singularity(16), Number of IP ranges(241)
Group(3), Singularity(15), Number of IP ranges(38723)
Group(4), Singularity(10), Number of IP ranges(142586)
Group(5), Singularity(8), Number of IP ranges(5336)
Group(6), Singularity(6), Number of IP ranges(113891)
Internet Service: 65646(Google.Gmail)
Number of IP range: 60
Number of IP numbers: 322845
Singularity: 15
Reputation: 5(Known and verified safe sites such as Gmail, Amazon, eBay, etc.)
Icon Id: 510
Second Level Domain: 53(gmail.com)
Direction: dst
Data source: isdb

Result

Because the IP and services related to Google Gmail on the Internet are included in this Internet Service (65646), all traffic to Google Gmail is forwarded by this policy

Destination IP Address of DHCP

When DHCP starts the client has no idea about the network it’s currently on. Some clients may store the IP address they were previously on and send this out with the Discovery and Request packets, but the network is not truly set up until after the server has sent it’s final Ack message. Because of this the server does not know the network’s true broadcast address, however there is an address mapped for this very purpose. 255.255.255.255 If you run arp -a you will see that every interface has the following mapping 255.255.255.255 ff-ff-ff-ff-ff-ff static This means that just like a networks broadcast IP this message will be transmitted to all network adapters on the local network segment. The DHCP server listens for messages heading for port 67 UDP while the DHCP client listens for messages on port 68 UDP Lets lake a look at a DORA sequence in Wireshark 148 16.564069 0.0.0.0 255.255.255.255 DHCP 342 DHCP Discover - Transaction ID 0xaccba128 149 16.5...
