[strongSwan] Host-to-Host Windows to Debian (StrongSwan)

[Ben Lavender]

Hello,

Please could anyone assist with this problem?

We have setup a connection between to servers (right Windows | left Debian-StrongSwan) in a host-to-host configure, where the Windows server will be establishing the connection using transport mode (IKEv1). The authentication is set to use a X.509 certificates.

The problem we are having seems to be within the two log lines below:

Oct 24 16:21:45 LAB-DEBCLIENT-01 charon: 07[ENC] parsed INFORMATIONAL_V1 request 62237808 [ HASH N(AUTH_FAILED) ]
Oct 24 16:21:45 LAB-DEBCLIENT-01 charon: 07[IKE] received AUTHENTICATION_FAILED error notify

Is there any advice given for attempting to resolve this issue? I can provide full logs if need be. Thanks.
