I need to map an external address to an internal address, and the same internal address back to the original incoming address, on a session by session basis. I cannot use automatic 1:1 mapping. I need to specify the addresses, which may not be sequential. For instance:
Internet-facing IP: 204.28.120.190/23
On a session-by-session basis:
Inbound source IP: w.x.y.z
Inbound target IP: 204.28.120.177
NAT: 204.28.120.177 (WAN) -> 10.10.10.30 (LAN)
Outbound source IP: 10.10.10.30 (LAN)
Outbound target IP: w.x.y.z
NAT: 10.10.10.30 (LAN) -> 204.28.120.177
There are a variety of options, like DNAT, SNAT, 1:1 NAT and full NAT. Does anyone know which one to choose, or how to set up a ocmbination, that works?
Thanks!
