Dear Hambourg, My response to your previous mail, > Below is my exact scenario -> Network 1 wants to communicate with Network 2 using NAT enabled router with two ethernet interfaces eth0(192.168.1.1) and eth1 (192.168.2.1). | Network 1 |---| NAT Router |---| Network 2 | (192.168.1.0/24) ^ ^ (192.168.2.0/24) | | eth0(192.168.1.1) eth1(192.168.2.1) > What I did is as mentioned below. >Step1: I am applying the following command "iptables -t nat -A POSTROUTING -s 0.0.0.0/0 -d 0.0.0.0/0 -o eth1 -j SNAT --to 192.168.2.1" in nat router. >Step2: Started initiating traffic(ICMP) from network 1 to network 2 and using wireshark I observed source ip of traffic from network 1 being translated to ip 192.168.2.1 in nat router. >Step3: With traffic from network 1 to network 2 in PROGRESS I am flushing the nat table using the command "iptables -t nat -F". > Now as there is no rule the sourece ip of traffic from network 1 should not be translated to ip 192.168.2.1 (which is my requirement), but it is being translated. > What should I do to fullfill my requirement. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
