HTTPS, Captive portal

Hello community!

Is it possible to change default HTTPS certificate to access admin panel? After that I need to block HTTP (allow only HYTPS). Can you share detailed instruction?

Is it possible to setup custom captive portal manually? As I know now it is not supported by firmware from the box.

Depends on the device. Newer devices (with fw >4.4) have the options within the settings available to force https.

Replacing the certificate does not make sense if you don’t know how to do it.

This & this

I am website owner. I know what is certificate. I want to generate personal one to make sure that there is no intrusion can happen

So I can tell you both devices (at least for the Opal I am sure) run with nginx. So replacing the cert is straight forward.

So I need to SSH into OpenWRT directly? There is no GUI for that?

Exactly.

You need to modify the files via SSH.
