Captive Portal Implementation with Wireless Router via Virtualbox

[jsonmat]

Hello everyone!

I am very new in pfsense and I would like to ask for help. I am on a macOS. I have Virtualbox installed. I installed the pfsense as a virtual appliance in virtualbox. I am able to configure it also using the WebGUI  from CentOS (also running in virtualbox).

My problem is that, how do I implement captive portal. I have a wireless router here. It is INTEX IT-G100RD.It has 1 WAN + 4 LAN ports + WLAN.

Is it possible to implement the captive portal with this router using pfsense in virtualbox?

Thanks in advance.
