How can i add a new certificat for the admin site of de firewall? I know I must have a root certificat.
What kind of certificate can you use if you don't have a CA?
Buy one and if so, what kind. I don't have a domain. Is only for the firewall


Best regards

    Hi @cateye  

    You can purpose third-party certification and import them into USG.

    e.g. GeoTrust, DigiCert, GlobalSign….etc.

    If using for these kind of certification as your HTTPS Web setting, then your browser may not pop-out “authority invalid” error before accessing to WebGUI.


    Of course you can generate certificate by third party tool. But the HTTPS connection to WebGUI may not secure enough.

    e.g. XCA.
