Zyxel NXC2500 [17/25] Portal redirection on managed ap application

NXC Application Note

Portal Redirection on Managed AP Application

Portal Redirection on Managed AP Application Introduction

It is ideal to have captive portal application for controllers and APs located in different

geographical locations or for hotspots without captive portal gateway deployment.

In FW release v4.20, captive portal redirect feature applies on the NXC controller only. From

FW v4.21, captive portal redirect on Managed AP is introduced, which enhances network

traffic efficiency without tunneling data traffic back to the NXC controller at the central site.

This provides more flexibility for web authentication configuration in both tunnel mode and

local bridge mode.

How Does It Work?

There are two portal redirect modes on the new firmware 4.21: redirect on controller and

redirect on AP. Redirect on AP is a new feature to process web authentication over distributed

APs to reduce centralized traffic loading on the controller.
