Hello, I would like to create a gateway in order to do a special kind of NAT. I need to do SNAT and DNAT in this way : SNAT : @src A.X.Y.Z -> A+1.X.Y.Z Example: @src 192.168.0.1 -> 193.168.9.1 @src 191.23.33 -> 192.23.33 DNAT : @dst A.X.Y.Z -> A+1.X.Y.Z Example: @dst 168.1.0.1 -> 169.1.0.1 @dst 154.9.2.36> 155.9.2.36 I know how to do it with "static list" of @IP with iptables : DNAT : iptables -t nat -A PREROUTING -d 192.168.0.1 -j DNAT --to-destination 193.168.0.1 SNAT iptables -t nat -A POSTOUTING -s 168.1.0.1 -j DNAT --to-destination 169.1.0.1 But, as I have a large number of @IP, how can I do it for ALL ip addresses ? Thank you for giving few secondes to explain me how to do it if you have an answer.
