Hi guys,
Can you take a look at this? :)
+-----------+
| |
eth1-|- |
| -|-eth0---LAN---
| |
eth2-|- |
| |
+-----------+
-
eth0 is connected to the LAN having the IP=LAN_IP
eth1 is connected to the first ISP having IP=ISP_IP_1 and GW=ISP_GW_1
eth2 is connected to the second ISP having IP=ISP_IP_2 and GW=ISP_GW_2
I need to selectively SNAT clients in the LAN to ISP_IP_1 or ISP_IP_2.
That would be something like:
$IPTABLES -t nat -A POSTROUTING -s 172.17.31.5 -j SNAT --to-source $ISP_IP_1
$IPTABLES -t nat -A POSTROUTING -s 172.17.31.7 -j SNAT --to-source $ISP_IP_2
This does not work since all the packets are forwarded to the default GW
which is ISP_GW_1.
How can I change this?
As far as I remember, the routing decisions and policy are before the
POSTROUTING chain in which the SNAT occurs...
Please help!
Mihai Vlad
