Transparent mode

To configure the FortiGate-VM to operate in transparent mode, you must configure the VMware ESXi server's virtual switches to operate in promiscuous mode to allow traffic that is not addressed to the FortiGate-VM to pass through it.

To configure virtual switches to support FortiGate-VM transparent mode:

1. In the vSphere client, select your VMware server, then select the Configuration tab.
2. In Hardware, select Networking.
3. Select Properties of vSwitch0.
4. In the Properties window, select vSwitch, then select Edit.
5. Select the Security tab, set Promiscuous Mode to Accept, then select OK.
6. Select Close.
7. Repeat steps 3 to 6 for other virtual switches that the FortiGate-VM uses.
