Hey there folks,
I'm trying to figure out how to configure my UFW, and I'm just not sure where to start. What can I do to see the intetnet traffic from individual apps so I can know what I might want to block? This is just my personal computer and I'm a total newbie to configuring firewalls so I'm just not sure how to go about it. Most online guides seem to assume one already knows what they want to block but I don't even know how/where to monitor local traffic to figure out what I can/should consider blocking.
You don't need a firewall on the LAN. It is just an annoyance to have to open ports later. Extra bureaucracy without benefits. This isn't Windows, you can can easily control your processes, choose if they bind to the network interface and on which port.
