@Tonyd For the guest portal you have 3 options Internal, External, and Facebook. For Internal you are just setting T&C and users log in. External has options for 3rd party authentication. And Facebook you set a URL to redirect to there business platform. When setting an SSID for Guest you have Open, Portal, and Password. Open is no securities, Portal is what was referenced above, and Password is using a PSK that supports WPA2 and WPA3.
