Hi,
I'm trying to do DNAT on a bridge.
This is the configuration of my network :
COMPUTER1 eth0 ------------eth0 BRIDGE1 eth1------------ eth0
COMPUTER2 eth1--------eth0 BRIDGE2 eth1--------- eth0 COMPUTER3
|eth2 _ _ _ _ _ eth0 COMPUTER4
@IPs :
192.168.1.1-------bridge1----- 192.168.1.2 | 192.168.2.2--------
bridge2 --------- 192.168.2.1
| _ _ _ 199.0.2.1
I try to du DNAT on bridge1 with iptables :
iptables -t nat -A PREROUTING -s 192.168.1.1 -d 192.168.2.1 -j DNAT
--to-destination 199.0.2.1
Without DNAT :
COMPUTER1 can ping COMPUTER 3 & COMPUTER4. So, my bridges look OK.
But, when I activate my little iptables rule, bridge1 seems to do
DNAT, packets are sent to bridge1 eth0 interface, but nothing seems to
be sent to computer2.
What did I do wrong ?
Thank you !
