So very lost wlxc interface? What is it? Should I worry?

I noticed a few days ago but just really started to look into it and I can't find any info on the net about it.
My networking skills are nothing short of sad but I am at a loss. I am worried about this because GUFW keeps blocking it so I think it might be bad?
Here it is
ifconfig

I have no idea what en2s0 or wlxc is...Please someone tell me not to worry.

Please provide the output of the following command:

lshw -C network

enp2s0 looks like your standard cable network interface
lo is the normal loopback interface
tun0 is your VPN interface

Which, depending on your machine specs would leave wlxc4e9841564f9 as some kind of Wi-Fi interface.

Edit: if you’re surprised because you’re not seeing the classic eth0 and wlan0 interfaces, it’s because it was changed recently and there’s a very good reason for that.

That output from lshw validates what I said in my previous post.
I wouldn’t worry too much about gufw.
I too have a lot of traffic that gets stopped by ufw and logged.
Most of it is multicast traffic.
It doesn’t hurt (me) to block it.

Thanks I Just Don’t understand what it is and why it would be there.[quote=“ouroumov, post:2, topic:7177”]
