Title: IPTABLES Firewall
Post by: Saif on August 21, 2004, 03:09:48 AM

Hi all,
I have created a iptables firewall file named 'firewall"  in /etc/rc.d and changed its mode to 711. In rc.local I have put 'sh /etc/rc.d/firewall'  but unfortunately the file is not being executed during restart.

When i run, sh firewall I get error message. But when I put the iptables one by one, all the rules are accepted.

Can any one help me. Thanks in advance

Saif

Sorry..I tried with your solution but it is not working. Please see the text inside that file(firewall). It is like this:

#!/bin/sh
IPTABLES=/sbin/iptables

$IPTABLES -F INPUT
$IPTABLES -F OUTPUT
$IPTABLES -F FORWARD

....... and bla bla bla

Then I did followings:
1. #chmod 755 firewall
2. #vi /etc/rc.d/rc.local
/etc/rc.d/firwall

Please note that I can run it if I put the commands
 sh /etc/rc.d/firewall
But none of the chains are accepted.

Now when i put the same chain directly it accepts all

I do not know why and where I am making a mistake.

Please help

With thanks and regards
Saif
