XG Firewall v18 Client Connect Failed to establish Child SA

I have configured my XG Firewall to use Client Connect with a preshared key. I have also set up a firewall rule to allow VPN to WAN. When I am connected to an external network and attempt to connect to the VPN, I receive an error that Client Connect failed to establish Child SA. I cannot find an answer online. I am new to Sophos and will need directions to access any logs needed. Thanks in advance for any help.

  • Hello TheCodeGeek,

    Thank you for contacting the Sophos Community!

    Please provide a screenshot of your Sophos Connect Client configuration in the XG, you can obscure the Public IP.

    Also please share the logs from the Sophos Connet Client, by click on the 3 dots and then click on Open VPN log.

    Please SSH to the XG, and press (5>3) and then type # cd /log and check the strongswan.log at the time the Sophos Connect client user is trying to connect.

    you can use

    # less strongswan.log 

    Regards,
