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.

Probably nothing bad happens with those faxes. A malicous actor would still need access to the physical analogue line or to the network to sniff the RTP packets (depending on how the fax is transmitted) on one of the two sides. In theory all providers involved could also sniff the traffic since calls/faxes are never end to end encrypted. But something could happen, and I dislike it very much that they demand their users to take this risk.

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.

Do they want you to fax them your Id?

Whatever this company is doing, stay away from it. This is ridiculous. Fax isn’t encrypted at all. Anyone asking you to do this has no idea about security and shouldn’t handle your data.

Also please don’t use some random fax app from the play store. They all seem sketchy as hell.

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

You can setup a freshrss server and connect readyou to it

Are you sure this is a DNS issue? If google.com can’t be resolved it shouldn’t run into a timeout. It should display an error message that google.com can’t be resolved pretty much instantly.
