I noticed this morning the iptables firewall was not starting due to the fact that I rebuilt the kernel and forgot to include the relevent Netfilter modules. So I added those and rebooted. The firewall still fails, but rather that referring to the non-available ip_tables module, it now just says iptables.init: iptables: Applying firewall rules: iptables-restore: line 13 failed.
I am currently going to port a Red Hat 6.4 machine and I need its firewall configuration, but something is going on.
iptables -L shows a list of rules as expected, but at the same time I can't find my /etc/sysconfig/iptables (or /etc/sysconfig/ip6tables). That's the first question I have: where is it getting the rules from?
