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.
This is not great advise to say the least. You want to block all incoming but allow all outgoing.
Also visiting a https site will not magically ports. It uses 443/tcp and if you are using a site with WebRTC (used for calls on platforms like teams) ports 443/UDP and 50000-65535/UDP. However, there is no reason you need to know that unless you are in a professional field
