Please help me with iptable setting

[onepasspress]

I have installed openVPN on my VPS server with tutorial provided from webhistingtalk.com but was unable to make it work properly.

after I installed openvpn and finished setting,

I did

Code: Select all

#echo 1 > /proc/sys/net/ipv4/ip_forward

#iptables -t nat -A POSTROUTING -s 1.2.3.0/24 -j SNAT --to xx.xxx.xxx.xxx <-my ip

openVPN connects fine, ping to server ip working but ping www.google.com or ping to outside of server does not work.

OpenVPN works fine if I delete all iptabes with

Code: Select all

#service iptables restart

then I am able to surf web with no problem. I am sure I have to do something with iptables but can't locate where it coming from.

Here's my iptables script
I really appreciate anyone's help in advance!!!

Code: Select all

#!/bin/sh
#
# 
#

set -e

echo 0 > /proc/sys/net/ipv4/ip_forward
