I'd go with the simpler rules close to those proposed by the list:
Code:
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -j ACCEPT -m state --state RELATED,ESTABLISHED
-A INPUT -i lo -j ACCEPT
-A INPUT -j REJECT
-A OUTPUT -j ACCEPT -m state --state NEW,RELATED,ESTABLISHED
COMMIT
