Hi
i'm using iptables for the first time..
masquerade work very well

but i would like to redirect an ip to another.. all ports
for example: 64.233.167.147 (google ip) to 192.168.0.11
so:
ping 64.233.167.147 .. will ping 192.168.0.11
telnet 64.233.167.147 will telnet to 192.168.0.11
ht1p://64.233.167.147/test.html .. will show ht1p://192.168.0.11/test.html

my setup:
192.168.0.10 is my server/router
192.168.0.20,21,22,... get internet acces from 192.168.0.10...

thanks
sorry for bad english..

iptables -A PREROUTING -d 64.233.167.147 -j DNAT --to 192.168.0.11

You forgot the nat table
[edit]
There is also another solution...

Add the IP in your /etc/hosts like:

cool it's working
thanks !

for the /etc/hosts.. it's what I used before .. but it<s local only.. so I needed to change hosts file of each computer...

and if I connect my laptop to another network.. (outside of my network) ... I want to use the "true" www.google.com

another question...
so.. www.google.com will be redirect to 192.168.0.11
because 64.233.167.147=www.google.com
btw.. www.google.com has 3 ip.. and if I do "iptables [..] -d www.google.com" .. one filter are added for each three ip.. but anyways.. my domain has only one ip
but what happen if www.google.com become 64.64.64.64
answer.. next time I restart my server.. or iptables script ..if I used "-d www.google.com" all will be okay ..

but i need to restart my server or my script..
idea ?

ps: it's so funny.. i think i will redirect www.altavista.com -> www.google.com for fews days.. and see if my users like it

iptables knows about ip addresses only. If you set up a rule using a fully qualified domain name it will do a lookup on that name and create a rule for all ip addresses found at the time the lookup is done. So, yes, if the ip address changes the redirect won't work anymore. If you want to redirect altavista to google you should think about setting up a squid proxy. Then you can instruct squid to rewrite requests for www.altavista.com to www.google.com. Using iptables DNAT will cause the URL in the address bar to still display www.altavista.com when people are infact seeing the google page. I guess that will be quite confusing to most users.
