Can I enable NAT on a specific interface only?

[pmaruszewski]

I have two interfaces in my Cisco 3600. I need to enable NAT outside on each, but they cannot use the same NAT pool. Where should I start? Is it possible to enable NAT pools on specific interfaces?

Yes, you can use different NAT pools on different interfaces. See the following URL for an example -

If I understand your question correctly, you want to NAT to different IP addresses depending on which outbound interface it uses. If this is the case, you should approach the problem using route-map. Configure access-list for destination IP addresses on the incoming interface and tie this back to the route-map statement. You are relying on routing to choose the correct outbound interface and hence the correct NAT address. Note that it's not possible to assign different NAT pools or static NAT addresses to different outside interfaces.
