Captive Portal with external Freeradius Server not receiving RADIUS response
** I think this should be the right category, as It's more a general question **
Using Pfsense 2.1.15
I managed to configure a Captive Portal using working fine.
Now I want to implement a RADIUS Server Authentication, but it's not working as it should.
The Radius server (freeradius) is running on a debian machine, IP 192.168.2.13/24, and is connected to OPT1.
Specific Clients connect though LAN Interface (192.168.1.1/24), on this Interface, CP is running and is connected to switch.
Any client that is connected to the LAN interface is redirected to the CP portal Page, 192.168.1.1:8002, so far working fine.
But when entering any credentials on the CP Page, any client will only receiv the message "Error sending request : No valid RADIUS responses received".
But when I check on Freeradius debug mode, I see that the credentials have been sent, and when valid, have been accepted.
So it looks like the response is not returned to the CP.
Also for test, I allowed full packet traffic from the OPT1 interface to LAN interface.
Still the same issue.
Please what could be the cause if this issue ?
Any help would be appreciated. I have attached some screenshots.
