iptables question

Hello ESG,

It is possible to give your iptables rule multiple '--to-destination' options.

It depends on the kernel-version you use.
There is a difference between kernels up to 2.6.10 and later kernel-versions,
so it is important to test this first.

good luck


Regards
Ron

Good morning,

I have a question about a specific usage of iptables. I need to forward the
incoming web trafic to 2 machines. I know how to forward to one, I use this:
iptables -t nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j DNAT
--to-destination 192.168.1.93:80

What I want to do is this:

MACHINE1 : IP1
MACHINE2 : IP2

all the trafic that comes to IP1 to the web port must go to the self IP1 and
to the IP2 to the web port.

Do you think this is possible ?

thanks in advance,

ESG
