I am running iptables with simple rule file, but its blocking cups, i am unable to open localhost:631, what rules should i add to iptable roule file to enable this. This is what current is there in my iptables rule file:

*filter
:INPUT DROP [0:0]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -i eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT 
COMMIT

Re: Iptables blocking CUPS

You need to allow the loopback:

-A INPUT -i lo -j ACCEPT

Other things will probably also break if you don't.
