NAT same server to different IPs

[sebastian.lemke]

Hi,

I am trying to implement the following NAT on a Cisco Router:

Server A (10.0.0.1) ----------- Router ------------ WAN

The server A communicates with 2 different networks in the WAN. For each of these two networks, server A must be natted to a different IP, let's say:

1. Server A communicates with network A --> NAT 10.0.0.1 to 172.16.0.1

2. Server A communicates with network B --> NAT 10.0.0.1 to 192.168.0.1

I suppose it won't work, when I just do

ip nat inside source static 10.0.0.1 172.16.0.1 route-map network_A

ip nat inside source static 10.0.0.1 192.168.0.1 route-map network_B

Because the second static NAT overrides the first...

When I do something like "ip nat inside source route-map...", it won't be possible to establish a connection from the outside to the inside. NAT will only work when the connection is established from inside to outside...

How can I implement this? Any ideas?

by the way, it's a

Cisco IOS Software, 2800 Software (C2800NM-ADVSECURITYK9-M), Version 12.4(25g)

Hello

ip nat inside source static 10.0.0.1 172.16.0.1 route-map network_A extendable

ip nat inside source static 10.0.0.1 192.168.0.1 route-map network_B extendable

what u have defined in route-map

works fine, thanks!

@Jawad: The route-maps contain an ACL, with a permit of the defined source and destination IPs for both connections.
