I have a NAT Router before a BGP Internet Router set up as follows:
LANs 1 and 2 ==> NATRouter ----> BGPRouter ==> ISP 1 and ISP 2
On the NAT Router, 2 distinct LANs (10.2.8.0 /24 and 172.16.0.0 /16) come in from 2 different Interfaces but go out towards the BGP Router through the same Interface. I have defined the 2 ingress interfaces as nat inside and the single egress as nat outside.
Using the same access-list and NAT pool everything works fine.
However I intend to use a different ISP on the BGP Router for the 2 LANs so i wish to define 2 NAT Pools such that LAN 1 uses one pool and LAN 2 uses another pool. But both traffic still go out on the same egress towards the Internet. I've read about using separate egress interfaces and a route-map in a multi-homed design but i only have one interface to use. Is it possible to have the 2 pools use the same interface somehow?
Our challenge is actually using 2 nat pools on the same interface with the nat outside command. Is it possible to have 2 nat pools work on the same exit interface. if not then we'll just find a way to move the nat to the ISP Router.
