Create default configuration of SD-WAN on FortiGate models with two WAN ports 7.6.5

This information is also available in the FortiOS 7.6 Administration Guide: Default SD-WAN configuration on FortiGate models with two WAN ports

FortiGate models with two WAN ports will have the following added to their default configuration:

• Both WAN ports are set to DHCP mode.

• An SD-WAN (sd-wan) zone is created, and both WAN ports are added as members.

• Default firewall policy utilizes the SD-WAN zone.

• An SLA is created, utilizing IP addresses 1.1.1.1 and 9.9.9.9 for internet connectivity evaluation.

Affected FortiGate models (where x can be 0 or 1): 6xE, 6xF, 7xF, 7xG, 8xE, 8xF, 9xE, 9xG, 10xE, 100EF, 10xF, 12xG, 140E, 20xE, 20xF.

To view the default configuration:

1. On a supported device, view the SD-WAN configuration:

   • An SD-WAN (sd-wan) zone is created.

   • The zone members include wan1 and wan2.

   • An SLA (Default_Ping) is created.

   show system sdwan
   config system sdwan
       set status enable
       config zone
           edit "sd-wan"
           next
       end
       config members
           edit 1
               set interface "wan1"
               set zone "sd-wan"
           next
           edit 2
               set interface "wan2"
               set zone "sd-wan"
           next
       end
       config health-check
           edit "Default_Ping"
               set server "1.1.1.1" "9.9.9.9"
               set members 0
           next
       end
   end

2. View the interface settings for wan1 and wan2 to see the mode is set to DHCP:

   • View settings for wan1:

     show system interface  wan1
     config system interface
         edit "wan1"
             set vdom "root"
             set mode dhcp
             set allowaccess ping fgfm
             set type physical
             set role wan
             set snmp-index 3
             config ipv6
                 set ip6-mode dhcp
                 set ip6-allowaccess ping
             end
         next
     end

   • View settings for wan2:

     show system interface  wan2
     config system interface
         edit "wan2"
             set vdom "root"
             set mode dhcp
             set allowaccess ping
             set type physical
             set role wan
             set snmp-index 4
             config ipv6
                 set ip6-mode dhcp
                 set ip6-allowaccess ping
             end
         next
     end

3. View the default firewall policy that utilizes the SD-WAN zone.

   show firewall policy
   config firewall policy
       edit 1
           set uuid 119c2598-b5ab-51f0-2303-861480a28741
           set srcintf "lan"
           set dstintf "sd-wan"
           set action accept
           set srcaddr "all"
           set dstaddr "all"
           set schedule "always"
           set service "ALL"
           set nat enable
       next
   end
