23.01 Radiusd pickup WAN all the time for auth instead of default WAN2 assigned.

Hi,

Some interesting behaviour noticed in system logs,
We have OpenVPN + 2FA via GoogleAuth implemented in place.
Default WAN for routing - WAN2, VPN server responds on WAN2, some time ago it was a WAN, and we switched, users and radius setup was done back to the time when WAN was default.

But now, even if a user connects correctly to the WAN2 channel, I see in the logs:

Feb 23 14:33:38	radiusd	75758	(11) Login OK: [username] (from client pfsenseclient port XXXX cli AAA.BB.CCC.DD:XXXX)
Feb 23 14:33:37	googleauth.py	76497	freeRADIUS: Google Authenticator - Authentication successful for user: username

and this IP address is the IP address of WAN.

Moreover, I have the situation, when 2 units netgate xg71001U with pfsense plus if it matters, were connected simultaneously to the internet, one of them via WAN2, and the second via WAN, they have a mirror setup.
So the interesting thing, while the users connected to the correct channel WAN2 on unit A,
unit B received this messages in the system log being connected via WAN.

I wonder where in the config files this can be adjusted to use the correct interface?

Thanks.
