Hello Imran,<br>
<br>
</span>You need to specify rightauth2=eap-mschapv2, so strongSwan is configured correctly to accept<br>
eap authentication using mschapv2 in round 2.<br>
<br>
You also lack the eap-mschapv2 modules, that you need for eap-mschapv2.<br>
Install it via your package manager or, if you built strongSwan yourself, configure the strongSwan sources with --enable-eap-mschapv2,<br>
"make uninstall" "make clean" "make" and "make install".<br>
<br>
Also, please make sure you send your answer to all parties involved, not just me.<br>
<span class=""><br>
Mit freundlichen Grüßen/Regards,<br>
