iptables - source ? destination ? From where ?
the question will sound stupid but in iptables, what is the point of reference for the "source" and "destination" feature.
I mean, you have your computer and internet.
Accept packet if destination port is tcp 80.
Does it mean allow the packet that goes from my computer to internet on tcp 80
allow the packet that goes from internet to my computer on port tcp 80 ?
Thanks in advance !
