Hi, I have a NAT box which has one private interface (eth0) on which I am running 2 different private IP ranges (192.168.2.0/24 and 192.168.3.0/24) I have eth1 which is connected to an ADSL modem and I have eth2 which is connected to a routable IP address I would like to SNAT 192.168.2.0/24 to eth1 and 192.168.3.0/24 to eth2 I am able to SNAT 192.168.2.0/24 to the ADSL modem connected on eth1 but I can't seem to get 192.168.3.0/24 to be SNAT to the routable IP address I had the following iptables rules iptables -P INPUT ACCEPT iptables -P OUTPUT ACCEPT iptables -P FORWARD ACCEPT iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -o ppp0 -j SNAT --to-source $ADSL_IP iptables -t nat -A POSTROUTING -s 192.168.3.0/24 -o eth2 -j SNAT --to-source $ROUTABLE_ETHERNET_IP The default route is set to go via the ADSL modem Any suggestions, do I have to do some form of policy routing and marking of packets prior to SNAT'ing them
