Mimic the default "Zones" from Ipfire in Opnsense?

[csmall]

I like the way ipfire uses zones with color codes to define the network.

WAN and LAN exist in OPNsense and correlate to red and green zones in ipfire.

In ipfire they use orange for a DMZ and Blue for wireless clients.

To mimic this, would I do the default installation on my quad port network card with WAN and LAN and then configure my OPT1 interface to be let's say Blue/Wireless and the last port I would add another interface and configure that as the DMZ?

Then I would attach my WAP to the blue/opt1 interface and create rules accordingly?

I'm probably over thinking this
