OpenWiFi 2.0
Creating a NAT Gateway is easily done via association to an interface having a role of "downstream".
Based on the above Dual SSID NAT configuration, a unique 2GHz and 5GHz SSID are created and logically bound to the same NAT LAN side network.
The NAT service is inherited by the downstream role with DHCP addressing defined according to the range set within the downstream "ipv4" configuration.

One of the benefits of the new data plane in OpenWiFi 2.0 is the flexibility of physical port to logical forwarding that is easily conveyed through configuration structures.
New protocol support is both easily added to the system as well as associated with interfaces by their role in the device.
The following sections offer feature configuration examples.
For complete reference to the device data model please refer here.

Creating logical bridges may be done through association to named "interfaces". To associate a logical SSID interface directly to the WAN, place SSID configuration within the interface have a "role" of upstream.

The most common use case for VLANs and Wi-Fi is likely the service provider, venue, enterprise where Wi-Fi traffic is not subject to address translation. This is the example that will be shown, however it is entirely possible to create multiple downstream VLANs with SSIDs as well. Simply replace the logic of upstream to downstream where desired.
In all cases the WAN port without VLAN id is using DHCP to obtain a management IP address. Each additional "upstream" role interface with an SSID associated have no IP configuration.
