How to remove the certificate errors for webadmin and captive portal authentication pages

TobLai

I have followed closely step by step on this KB.

https://support.sophos.com/support/s/article/KB-000036904?language=en_U

I still cannot get rid of the Not secure warning by the browser. Am I missing something here?

Ot do I need to buy my own CA Certificate?

    By default in XG, when the web proxy redirects a user to the firewall it uses the IP of the firewall which cannot be covered by a certificate. To redirect to the hostname instead, see the following:

    Sophos XG Firewall: Use hostname for page redirects


    In XG 17.5, the hostname used in redirection settings can be found at Administration > Admin Settings.

    It is possible to configure the captive portal to be displayed in HTTP rather than HTTPS and therefore not require a certificate. However, this is not recommended because passwords would be sent across the network unencrypted.
