Thanks for the reply, following that article only setup the Firewall and NPS, when connects the WiFi receives the error "Received from Invalid RADIUS Client" which shows my AP IP.

As explained above i am using UniFi Access Point which IP is already exists in my SOPHOS Firewall, In UniFi AP configuration under RADIUS option i entered my RADIUS Server IP, i don't know if i speculate right, under AP RADIUS Server Details instead of RADIUS server IP should i give my Firewall IP???

Attached Pictures are for reference.

I am not quite sure about the Client, but the Radius Client should be the XG firewall. 

Do you have a contact to UniFi to get this checked by UniFi? 

Found an old post in Sophos Community about the framed IP, but this should only be necessary for Radius Accounting.

Yes i checked with UniFi support but my bad luck, the support person instead of saying any clue just said they are not supporting for 3rd party device!

I configured according to previous shared article unfortunately in that article there is no point of any AP configuration such that to understand how the setup completely configured.

Are you capable of analyse tcpdumps in wireshark ? 

It would be possible to dump those Radius Requests into one tcpdump, download this dump and check out the dump in wireshark.

Afterwards you would be able to simply google the outcome of those invalid Radius requests to get a clue about, what is going on.

Unfortunately i do not have any Radius framed infrastructure to give you any hint, but the process above would be my way to go to get a better understanding, what is going on.
