Ikev2 + eap-radius + client certificate not working

Hi
Im trying to implement Ikev2 with eap-radius using client certificate
Eap-radius work great when use username and password but when im trying to use a certificate Mikrotik send the Client ip adderss as Username to the radius authentication
and then fail.

Any idea of what is wrong?

Hi i already see the problem

Mikrotik is sending as username the ip address of the client instead of the user stored on the certificate
Is a bug ? or i have to set a especial extension to the certificate that mikrotik can send the realm?
