Using wildcard FQDN addresses in firewall policies

You can use wildcard FQDN addresses in firewall policies.

The firewall policy types that support wildcard FQDN addresses include IPv4, IPv6, ACL, local, shaping, NAT64, NAT46, and NGFW.

When the wildcard FQDN gets the resolved IP addresses, FortiOS loads the addresses into the firewall policy for traffic matching.

To create a wildcard FQDN using the GUI:
  1. Go to Policy & Objects > Addresses and click Create New > Address.
  2. Specify a Name.
  3. For Type, select FQDN.
  4. For FQDN, enter a wildcard FQDN address, for example, *.fortinet.com.
  5. Click OK.
To use a wildcard FQDN in a firewall policy using the GUI:
  1. Go to Policy & Objects > IPv4 Policy and click Create New..
  2. For Destination, select the wildcard FQDN.
  3. Configure the rest of the policy as needed.
  4. Click OK.

    In this example, policy ID 2 uses the wildcard FQDN:

To create a wildcard FQDN using the CLI:
config firewall address
    edit "test-wildcardfqdn-1"
        set uuid 7288ba26-ce92-51e9-04c0-39c707eb4519
        set type fqdn
        set fqdn "*.fortinet.com"
    next
end
To use wildcard FQDN in a firewall policy using the CLI:
config firewall policy
    edit 2
        set uuid 2f5ffcc0-cddc-51e9-0642-ab9966b202dd
        set srcintf "port3"
        set dstintf "port1"
        set srcaddr "all"
        set dstaddr "test-wildcardfqdn-1"
        set action accept
        set schedule "always"
        set service "ALL"
        set auto-asic-offload disable
        set nat enable
    next
end
To use the diagnose command to list resolved IP addresses of wildcard FQDN objects:
diagnose firewall fqdn list
List all FQDN:
*.fortinet.com: ID(48) ADDR(208.91.114.104) ADDR(208.91.114.142) ADDR(173.243.137.143) ADDR(65.104.9.196) ADDR(96.45.36.210)
*.google.com: ID(66) ADDR(172.217.14.238)
login.microsoftonline.com: ID(15) ADDR(40.126.7.64) ADDR(40.126.7.65) ADDR(40.126.7.66) ADDR(40.126.7.97) ADDR(40.126.7.99) ADDR(40.126.7.100) ADDR(40.126.7.101) ADDR(40.126.7.103)
To use the diagnose command for firewall policies which use wildcard FQDN:
diagnose firewall iprope list 100004
policy index=2 uuid_idx=46 action=accept
flag (8050108): redir nat master use_src pol_stats
flag2 (4200): no_asic resolve_sso
