Issue Description

From the config:


interface LoopBack1
 description buil_in_portal
 ip address 10.10.10.1 255.255.255.0  (portal address interface)

portal local-server ip 10.10.10.1  (portal address)

interface Vlanif101
 description SERVICE VLAN FOR STA
 gateway-list 192.168.3.105    (internet gateway for STA)
 ip address 192.168.3.55 255.255.255.0   (AC address)
 dhcp select global

The portal page is correctly pushed after the wifi connection, but it is blank:



Handling Process

In this situation the station is connected to the wifi network but not to the portal. You can check with:

Solution

put the static route to the portal address ip in the gateway with the AC ip as next hop:


This time the portal will appear on the web page and will authenticate the user:
