NAS IP Attribute / Authentication Servers

Hi all

I saw the Youtube Video (https://youtu.be/jEK-O3U3gdg?t=346) and i wondering now why did you set the NAS IP Attribute to LAN?

I have only WAN and OPT1 beause i deactivated LAN. Is there a reason not to stay on WAN?
I use it with IPSec and FreeRadius (Interfaces with 127.0.0.1).

@LTS_Tom Keep on with your lovely Videos.

Many Thanks

Found it.

It was WAN before. So no reason to change for me.

Well that took me a long time to find.
