Sophos XGS V19 Web Certificates and browser warning pages

Hello,

Starting to get a bit frustrated with the Sophos web certificates - think I am going around in circles.

I have both the Default Appliance certificate and the Security SSL Certificate installed into the Trusted Certificates store on a Windows 10 Pro Laptop via management console.

Firewall rule is configured to use DPI engine for web filtering with a web filtering policy.

Every time I test the web filtering, Google Chrome always shows the "page not secure" warning with the URL showing the IP address of my Sophos Firewall.

What am I doing wrong?

I remember reading something about using FQDN instead of IP addresses - but I not fully sure if that resolves my issue? Would that have something to do with the Default Appliance certificate?

What do I need to configure to ensure that the Sophos Web Filtering Block page is displayed first time round when using the DPI-SSL web filtering?

Thanks.

  • An observation for what it is worth. My w10 Pro fully upto date, IE recognises and uses the XG CA, edge does not.

  • Hello,

    When viewing the certificate in the browser - it shows it as the Appliance issued by the Default certificate.

    The status message for both certificates are "Certificate is OK".

    The only thing that I am thinking of is something to do with FQDN and host redirects - but I don't know where to configure that so that the certificate relates to the host name of the Firewall instead of the IP address.
