The iptables -L doesn't show any interface, only "RH-Firewall-1-INPUT" as the "target" field. I have tryed the command under with $YOUR_INPUT_INTERFACE set up to RH-Firewall-1-INPUT, but it showed "interface name `RH-Firewall-1-INPUT' must be shorter than IFNAMSIZ (15)". What´s I'm doing wrong, please? TIA, Vinicius.
