I have a bunch of public IP addresses, for example, in the range 192.168.1.100-192.168.1.104. I have a 5 computers on my internal network statically defined from 192.168.0.100-192.168.0.104. I am trying to create a rule where each computer will always map to the same public ip address. For example I did: iptables -t nat -s 192.168.0.100 -j SNAT --to-source 192.168.1.100. The problem is if I try to do a ping from 192.168.0.100 it correctly gets translated to 192.168.1.100 and the ping goes out, but when the reply comes back there is an ARP request for WHO-HAS 192.168.1.100, and since no-one technically holds this address no reply is ever sent, and the ping reply gets dropped. Does anyone know a solution to this problem?
