Hello, My objective is if ip A.A.A.A goes to B.B.B.B it is natted with IP X.X.X.X then if A.A.A.A re-establishes a session with B.B.B.B it is natted with the same IP X.X.X.X. According to my reseach the module ipt_same does that: SAME (IPv4-specific) Similar to SNAT/DNAT depending on chain: it takes a range of addresses (`--to 1.2.3.4-1.2.3.7') and gives a client the same source-/destination-address for each connection. But seems like the module ipt_same is not available under iptables v1.4.21 Kernel: 3.16.7. Are there any module available that can help achieve my objective? Thanks.
