[strongSwan] strongswan network manager client using eap-radius

[Martin Willi]

Hi Clause,

> Jun  3 08:21:38 vpn6-test charon: 10[IKE] received EAP_NAK, sending EAP_FAILURE

Seems that the client does not like the EAP method offered. I assume
you're using MSCHAPv2, so double check that the client has the
eap-mschapv2 and the eap-identity modules installed and loaded.

For more information about the client error, have a look
at /var/log/daemon.log.

Regards
Martin
