I have updated newest snapshot, it seems that IKEv1, PSK + XAuth is working.
I am trying IKEv1, RSA but failed (I tried IKEv2, EAP-TLS but failed then step back to IKEv1).
I am not sure if the certificate has issue (I use the Cert Manager on pfSense to create the certs, CA, it is quite useful if things work)
Thank you for your recomment.
