Network interface selection is very important while creating a wireless SSID profile.
Let's go through the common scenarios and interface selection.
1) Gateway Mode:
Ray in only Gateway mode is a simple and common scenario for the home-based wi-fi internet setup as displayed in below
picture.
In this case of gateway mode only interface selection will be as explained in the following snapshot.
It is not always mandatory for particularly Ray gateway mode AP SSID profile to select any interface under "Gateway" field.
You can leave it blank the "Gateway" filed without selecting any Interface. check below snapshot.
All 4 fields indicate the different possible modes with Ray APs.
In only Gateway mode, the network interface needs to be selective in the Gateway section of the SSID profile window.
The rest of the options are for other modes and network scenarios.
Why to chose the LAN interface for SSID in Gateway only mode?
Its because the LAN interface will be the gateway interface for both wired and wireless clients connected with the network.
And interface selection will behave based on the AP you have setup in a particular mode.
2) Bridge mode scenario:
If your AP receives the IP Address via DHCP then, none of the settings except WLAN need to be created.
In this case, the Default WAN will already have the IP Address via DHCP.
The Ray AP shall be in "Bridge Mode" with the WAN Interface.
AP with bridge mode is almost similar to the AP in individual client mode with different gateway than Ray AP.
But AP with bridge mode will enhance and extend the services like captive portal access for the guest users,
policies pushed by the gateway firewall, etc. with client mode these things are not possible to work with.
In the below snapshot is the best example of a "Heterogeneous network" for bridge mode APs.
Network interface selection for bridge mode Ray AP will be just like marked in the below snapshot.
For a simple scenario with Bridge mode, without VLAN configuration in your infra, you don't need to
create any interfaces or even you don't need to select any interfaces, as for the SSID profile template
we have kept it selected for the best configurations by default.
Configurations shown in the below snapshot is by default in the template for simple SSID without any
manual interface creation.
3) Client mode:
The client mode is the same as Bridge mode with one key difference.
Unlike Bridge mode, client mode has the firewall turned off and it purely works as a client.
The ideal use case of client mode is behind a firewall or an SD-WAN gateway.
Below is the best example of a "Heterogeneous network" for client mode APs.
Network interface settings for the Client AP with other gateways will be as given in the following snapshot.
