iptables NAT to ip pool

saavik · 10-02-2008, 06:08 AM

Hello!

I would like to NAT on net to the other net, but I can not always user the same ip as:

Quote:

iptables -t nat -A POSTROUTING -s 10.0.0.0/8 -o eth1 -j SNAT --to 188.0.0.1

would do.

So I found this

http://lists.netfilter.org/pipermail...ch/008924.html

page which says that I can use a ip pool as SNAT --to option.

When i type :

Quote:

# iptables -t nat -A POSTROUTING -s 10.0.0.0/8 -o eth1 -j SNAT --to 192.193.50.0/24
iptables v1.3.5: Bad IP address `192.193.50.0/24'

What is my mistake ?

Do both net`s have to be class "A" ? I am on RTFM .....

Ok, I got it working with

iptables -t nat -A POSTROUTING -s 10.0.0.0/8 -o eth1 -j SNAT --to 9.0.0.0-9.255.255.255
