You can't install a root CA in Firefox for android.

You have to install the cert in android and set Firefox to use the android truststore.

You have to go in Firefox settings>about Firefox and tap the Firefox logo for a few times. You then have a hidden menu where you can set Firefox to not use its internal trust store.

You then have to live with a permanent warning in androids quick setting that your traffic might be captured because of the root ca you installed.

It does work, but it sucks.

If you're using a /24 network the IP shown in the screenshot is the broadcast IP of your network.

445 is the default port for smb. It should be the same on every os if you didn't manually chang it. 80 is http by default. Did you maybe set it for a Webinterface?

Try adding it manually and enter the IP of your smb server, port 445 and the user/password you set for smb.

I like firewalld. Its also used on many enterprise distros (RHEL, SLES).

But if you just have to open one port for something, just use what's installed on your distro.

You always need to recreate the container when you change something in the compose file. Did you double all $ signs in the hashed string?
