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.
In a nutshell,
Use wireshark
See if theres any weird connections going on (i.e you visit pancakes.com and wireshark shows unrelatedsite.com making a request as well)
Block unrelatedsite.com
Block from ports 1000 'till the very end (65565 if I’m not mistaken.) – that is your “bread and butter” approach.
Nah, you (very likely) aren’t and never will.
