On my RHEL 6.2 server, in my /etc/sysconfig/iptables, I have
:INPUT ACCEPT [0:0] but I cannot access files through web server on port 80 unless I add a rule like this:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
Please clarify why. Thanks. According to this post, I shouldn't need that additional entry.
