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 shouldn’t be touching it, honestly. There’s a firewall at your router. It should be responsible for blocking incoming traffic. Firewalls on individual machines are for servers where you know exactly what’s going in and out. I don’t have a firewall on my desktop or laptop.
You will spend the best years of your life chasing random network connections if you block everything by default.
This is good sane advise. I think a lot of people here don’t understand networking
