NAT routing to an interface

[mwtillman]

I am trying to route all incoming traffic for tcp ports 9000 to 15000 on Cellular 0/0 to GigabitEthernet1 and all incoming traffic for tcp ports 9000 to 15000 on Cellular 1/0 to GigabitEthernet2.

Everything I am finding shows how to route to an IP address. Is there a way to route interface-specific traffic to specific interfaces?

TIA

Hi

What do you mean by nat routing in your title?

Based on your description you want to for to specific interfaces based on tcp ports for inbound traffic on your cellular interfaces. This can be achieved using PBR (policy based routing).
The goal with PBR is to define an acl, and based on that all (using a route-map) you'll tell the router to go to a specific outside interface or a specific next hop ip.

I won't type all commands because there is a great post done to explain each steps:
