I have a 1711 running 12.4 and already have NAT running in overload from all inside interfaces to the outside. This works fine without issue.
In order for traffic to be routed through the 3rd party CRM gateway, the traffic needs to have a 161 address. I would like to configure the router to NAT all traffic coming in on VLAN 160 to have an address on the 161 VLAN.
Below are the relevant lines in the existing configuration:
interface FastEthernet0
description FastEthernet0: Outside
ip address 4.xx.xx.154 255.255.255.252
ip access-group 109 in
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
ip flow egress
ip nat outside
ip inspect holiday out
ip virtual-reassembly
ip route-cache flow
duplex auto
speed auto
no cdp enable
!
....
interface FastEthernet3
switchport access vlan 160
!
....
interface Vlan160
ip address 10.28.160.253 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
ip nat inside
!
interface Vlan161
ip address 10.28.161.253 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
ip flow egress
ip nat inside
ip virtual-reassembly
!
....
!
ip nat pool ovrld 4.xx.xx.154 4.xx.xx.154 netmask 255.255.255.252
ip nat inside source list 7 pool ovrld overload
....
access-list 7 permit 10.28.161.0 0.0.0.255
I'm thinking that I need to use a Route-Map to identify the correct interface but I'm not certain that you can mix access list NAT with route map NAT and how you would go about implementing it.
I appreciate any help you may offer.
