Captive portal + freeradius server on LAN problem

[spacemind]

Hello,

I have setup a freeradius server in my LAN to get the captive portal working with, but the pfsense sends the auth request to freeradius with the wrong ip address.

Network:

Pfsense(router WAN 84.90.120.xxx LAN 192.168.50.254)  – switch -freeradius(192.168.50.200)
                                                                                          -access points(as bridge)  --- clients

When Pfsense sends the auth packets do freeradius from LAN the freeradius server get the requeste but with the WAN ip from pfsense.

The freeradius server is with passtrough ip and macaddress in pfsense.

I need the pfsense to send the radius request with the LAN ip, not the WAN ip.
