How to set up your FortiWAN
Configuring Network Interface (Network Setting)
9. In the Netmask field, enter [255.255.255.0].
10. In the DMZ Port field, enter [Port 3].
11. In the IPv4 Static Routing Subnet field, use [+] to add new rules with Subnet Type as [Subnet in DMZ]. In this
example, there is a router in the DMZ port for the public IP subnet and the subnet does not connect to the
FortiWAN directly. Therefore the subnet info should be filled in the "Static Routing Subnet" field.
12. In the Network IP field, enter [211.20.104.0].
13. In the Netmask field, enter [255.255.255.0].
14. In the Gateway field, enter [211.20.103.253].
15. Go to [WAN/DMZ Private Subnet] sub-function page and select [+] in the IPv4 Basic Subnet and add the following
rules:
16. Set the Subnet Type as "Subnet in WAN".
17. In the IP(s) on Localhost field, enter [192.168.0.253].
18. In the Netmask field, enter [255.255.255.0].
19. In the WAN Port field, select [Port 1], and the configuration is complete.
WAN Type: Routing Mode Example 3
In this example, both WAN links have its own routers and FortiWAN is connected to these routers using private IP
addresses, as illustrated below. In addition, FortiWAN Port 3 has been assigned another private IP connecting to the
LAN Core Switch (L3 switch), therefore there is a public IP subnet connected behind the Core Switch inside the LAN.
Configuration Example:
1. FortiWAN Port 1 (192.168.0.253) is connected to WAN1's router (192.168.0.254/24).
2. FortiWAN Port 2 (192.168.1.253) is connected to WAN2's router (192.168.1.254/24).
3. FortiWAN Port 3 (192.168.2.253) is connected to the LAN Core Switch (192.168.2.254/24).
4. WAN1's Public IP subnet is placed behind the Core Switch as (211.70.3.0/24).
5. WAN2's Public IP subnet is also placed behind the Core Switch as (53.244.43.0/24).
