Sophos XG125 - Disable captive and show Authentication error message

Hi WebShieldNerd,

Thank you for reaching out to the Community! 

If you uncheck the option "Use web authentication for unknown users" from the firewall rule, unauthenticated requests are allowed. If the requests are blocked due to the web policy, users will be authenticated.

There's no option for the customized message without a captive portal when an unauthenticated user tries to access the internet. 

However, you can customize the captive portal appearance; please check out the following document for more information. 

• Web authentication

Thanks,

Ahh. That makes clear. Now changed the CaptivePortal html code and removed user input form to look as 'Unauthenticated User' error message.

..and it worked.

Thanks Harsh.

Hi WebShieldNerd,

Thank you for the update. I'm glad to know that you resolved your issue with the custom Captive Portal HTML code. 

Thanks,
