Hello! Just one question... I have a firewall with the INPUT, OUTPUT and FORWARD policies set to DROP, and now I want to allow connections from localhost to localhost (any port). Which chains are implied here? INPUT? OUTPUT? Both? How should the needed rule(s) be?
Thank you very much in advance!

I put these simple rules in my INPUT and OUTPUT chains. I checked the counts, and these handle the most traffic, so I put them first in their chains.
# accept packets originating on this machine iptables -A INPUT -i lo -j ACCEPT
# allow packets from this machine to this machine iptables -A INPUT -o lo -j ACCEPT
I hope that helps.
