[gentoo-user] iptables configuration problem

["Chuanwen Wu" <wcw8410@gmail.com>]

Hi,guys!
I use iptables to let the PCs in the subnet to connect the internet outside.

And i write a simple script,but it doesn't work:

#!/bin/sh
iptables -F
#Define packets from Internet server to Intranet
iptables -A FORWARD -d 198.168.1.0/24 -i eth0 -j ACCEPT
#Define packets from Intranet to Internet
iptables -A FORWARD -s 198.168.1.0/24 -i eth1 -j ACCEPT


Here is the result of iptables -L:

# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy DROP)
target     prot opt source               destination
ACCEPT     all  --  anywhere             198.168.1.0/24
ACCEPT     all  --  198.168.1.0/24       anywhere

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination


The eth0 here has the real ip,and the eth1 have a subnet ip:192.168.1.21.
How to fix this problem?All I need now is just to let my office
machine to use the internet!
Thanks in advanced!!
