I am a new user of Fedora 30. I connect my laptop through wifi provided by smartphone hotspot (Android)
My computing equipment was compromised, and this is what motivated me to adopt Fedora.
I configured my firewall to the block zone, and through nmcli, I set the connection to be private. I have no incoming connections to the machine in any other way, and I really would prefer to have no incoming connections. Everything was working fine until a couple of days ago, when “nmcli con” reported a secondary connection “virbr0.” I am not well versed in networking, but I think this has something to do with a digital bridge.
Again, I am not doing anything to connect into the laptop from any device, so I am puzzled by this “virbr0” connection. I deleted it, and it keeps popping up.
Could you help me figure out how I would block/disable this type of device with the firewall? Or any other way? I am just using an internal wireless card to connect wirelessly to the smartphone, which gives me the connection through hotspot.
