Retail Store FortiGate Dual-WAN VLAN Topology
Drawing preview
The scenario

A retail store needs dual WAN failover via FortiGate 40F while isolating POS, surveillance, and guest Wi-Fi traffic into separate VLANs.

What is in this drawing

Read the decisions behind it.

01

Model two ISP links to the FortiGate for primary/backup WAN failover

02

Use VLAN 10 for POS, VLAN 20 for surveillance, VLAN 30 for guest Wi-Fi

03

Place edge firewall and core switch tiers to show segmentation hierarchy

Use when documenting a small-branch FortiGate dual-WAN setup with VLAN-separated operational traffic.
