Service iptables Restart brings up an unknown failure message, must ensure security

Hi,

I have recently installed and set up a new server and had just finished setting up the iptables document in /etc/sysconfig/iptables and when I restarted the page I received this error:

Flushing firewall rules:                                   [  OK  ]
Setting chains to policy ACCEPT: security raw nat mangle fi[FAILED]
Unloading iptables modules:                                [  OK  ]
Applying iptables firewall rules:                          [  OK  ]


My iptables pages looks like this:

# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]

Any help or observations on this matter would be great!

I suppose You can ignore this.
most probably it's because one of the mentioned tables is unsupported by this kernel build
try
for i in security raw nat mangle filter; do echo $i; iptables -t $i -P INPUT ACCEPT

Also, what linux distro You have installed, maybe it has the bug, that every table has different chains?
