Ipsec: Creating local authentication data failed

J.Janssens

When trying to connect the tunnel, I get the message "Creating local authentication data failed" in the log files and the tunnel is not established. 

The few hits on Google talk about missing the local and/or remote ID, but I did enter those.

My settings (fictive IP addresses):

Name
Test

IP version
IPv4

Connection type
Site-to-site

Gateway type
Initiate the connection

Policy
IKEv2

Authentication type
Preshared Key

Listening interface
212.162.1.1

Local ID type
IP address

Local ID
212.162.1.1

Gateway address
212.23.5.5

Remote ID type
IP address

Remote ID
212.23.5.5

    Hello J.J

    Thank you for contacting the Sophos Community.

    Adding to what Carbon15 mentioned, this issue is usually related to the PSK being used, so a mismatch.

    But as Carbon15 said, checking the charon.log and strongswan.log in debug mode might give you more info on the error.

    Regards,
