Configuring Network Interface (Network Setting)
How to set up your FortiWAN
As illustrated in the topology below, FortiWAN port1 are mapped to WAN port. Port2 and port3 are configured as the
redundant LAN ports which are connected to Switch1, port4 and port5 as the redundant DMZ ports which are
connected to Switch2. In this case, once one of the two LAN/DMZ links breaks down, FortiWAN will enable the other
LAN/DMZ link to resume the traffic.
Configure [VLAN and Port Mapping] from the Web UI. In this example, Port 1 is set as WAN, Port 2 and Port 3 as HA
LAN port pair and Port 4 and 5 as HA DMZ port pair. Each of the LAN/DMZ pair is connected via a single switch (switch
1 or switch 2). This will remove the chance of single point failure on the switch, and the entire system will be in ‘HA’.

After applying the configurations above, the options "Bridge: lan23" and "Bridge: dmz45" are listed respectively in the
pull-down menus of LAN Port and DMZ Port for WAN Setting, WAN/DMZ Private Subnet and LAN Private Subnet. For
aggregated LAN/DMZ, the options "Bonding: label name" will be also listed in associated menus.
