error in /etc/sysconfig/iptables

[Bailey Kong]

There are a 2 ways you could go about this, the first way, is to load your
script from another location like /home/user and
do /etc/rc.d/init.d/iptables save
and that will saving it to /etc/sysconfig/iptables in the format they want
it and to put the ip_forward at "1" everytime you boot, in /etc/sysctl.conf
there's this line

net.ipv4.ip_forward = 0

just change the 0 to 1 and saving the file.

the second method is to edit the /etc/rc.d/init.d/iptables

   for i in $chains; do iptables -t $i -Z; done

            echo $"Applying iptables firewall rules: "

                # comment out
                #grep -v "^[[:space:]]*#" $IPTABLES_CONFIG | grep -v '^
[[:space:]]*$' | /sbin/iptables-restore -c && \
                # manually add in
                exec $IPTABLES_CONFIG && \
                    success $"Applying iptables firewall rules" || \

comment out the grep line, and add the exec $IPTABLES_CONF && \
save the file and you should be all set
