Hi. I wanted to know if it’s needed to install a firewall on a linux desktop/laptop. Why yes or why no?
minus-squareTurunlinkfedilink14•2 years agoIf you allow the whole subnet you might as well not use a firewall. Your router has one and port forwarding is disabled by default.
minus-square@BrianTheeBiscuiteer@lemmy.worldlinkfedilink0•2 years agoYeah, I kind of agree. Unless this is a mobile device pretty much all traffic will come from within your subnet. I often deny incoming from my gateway (i.e. router) and poke holes as necessary.

minus-squareTurunlinkfedilink2•2 years agoThanks. So docker manipulates iptabels directly, thereby bypassing ufw rules. (Your previous comment was just really vague)

ufw and docker don’t like each other
Can you elaborate on that? I’m curious what you mean.
