Hello, i have been using UFW for years and decided to switch to using iptables, however there is something i do not understand.
with UFW i used to enable, start on boot, then DROP all INCOMING and ALLOW a few OUTGOING rules.
on iptables, it seems that ACCEPT OUT and DROP INCOMING disables all network traffic, then after allowing a few INCOMING rules, i can establish traffic.
why is this difference between UFW and iptables regarding blocking INCOMING traffic?
is it safe to allow a "few" INCOMING traffic?
is there a way to drop all INCOMING traffic on iptables just like with UFW and still establish internet connectivity?
