Dear All

SUSE server IP is 192.168.0.25,because my firewall just can do 1 to 1 NAT, I want to 1 WAN IP can use in 2 different LAN

I would like to ask if I want to set NAT function, is it must have 2 lan card?
Can I just configure it with 1 lan card??

because I just want to redirect port 80 to my web server

I have write a script but it is not work? where do I wrong?


Please advice

Thanks


here is my script

#! /bin/bash

modprobe ip_nat_ftp
modprobe ip_tables

iptables -F
iptables -X
iptables -Z

iptables -t nat -F
iptables -t nat -X
iptables -t nat -Z

iptables -t mangle -F
iptables -t mangle -X
iptables -t mangle -Z

iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT

iptables -t nat -P INPUT ACCEPT
iptables -t nat -P OUTPUT ACCEPT
iptables -t nat -P FORWARD ACCEPT

iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to 192.168.0.5

Not sure if it will help in this instance, but I have used Shorewall http://www.shorewall.net/index.htm with great success and can say it definitely makes setting up iptables easy, just like their tagline says. It works these things out for you by setting up simples rules, definitely worth checking into. Good luck!
