NAT Question

[mjc28]

Is it possible to NAT two external IPs to one internal IP? How would this be done?

We have customers transferring data to our (.103) server and rather than giving them a new IP, we thought it would be simpler to NAT.

I currently have a 1:1 relationship with external to internal IPs but due to constraints, we are consolidating a server and need to move external access to another box. All external IPs are NATed on our ASA 5520.

In the example below, we are shutting down server with x.x.x.103 and need to move accounts to server x.x.x.101 or ..102. It should be noted .101 and .102 are on the same box, I'd be adding a third IP


static (inside_1,outside_0) x.x.x.101 10.1.1.10 netmask 255.255.255.255
static (inside_1,outside_0) x.x.x.102 10.1.1.11 netmask 255.255.255.255

static (inside_1,outside_0) x.x.x.103 10.1.1.13 netmask 255.255.255.255

Thanks in advance,

On your server, can you add multiple 10.x.x.x IP addresses to the server NIC. This way you dont have to change the external to internal mapping.
