Hello,
I am trying to configure two inside interfaces without NAT. I am not using nat-control and I have added exemptions for the two networks. I can communicate between the two networks and to the Internet just fine.
I would like to verify that NAT is disabled between the two interfaces. I also need to make sure that the Interface IP (specifically for the traffic from inside-test to the inside network) is not added to packets between the two networks. I would like to be able to verify this as well. In other words I need to have the Source IP address from the originating connection on the inside-test network passed along through to the Inside network device without being replaced by the Interface's IP address. This is a test config for a production environment that will be using a load balancer. The config I have may be working in this regard and the load balancer may be replacing this IP address (that is what I am trying to test), but I am not certain.
So far I have the following NAT related running-config command (in regards to these two interfaces):
access-list NAT_Exempt extended permit ip 192.168.12.0 255.255.255.0 interface inside
access-list NAT_Exempt extended permit ip 192.168.3.0 255.255.255.0 interface Inside-test
access-list NAT_Exempt extended permit ip 192.168.12.0 255.255.255.0 192.168.3.0 255.255.255.0
access-list NAT_Exempt_2 extended permit ip 192.168.12.0 255.255.255.0 interface inside
access-list NAT_Exempt_2 extended permit ip 192.168.3.0 255.255.255.0 interface Inside-test
access-list NAT_Exempt_2 extended permit ip 192.168.3.0 255.255.255.0 192.168.12.0 255.255.255.0
nat (inside) 0 access-list NAT_Exempt_2
nat (inside) 1 0.0.0.0 0.0.0.0
nat (Inside-test) 0 access-list NAT_Exempt
nat (Inside-test) 1 0.0.0.0 0.0.0.0
global (outside) 1 interface
global (Inside-test) 1 interface
Let me know if more information is needed for you to assist me futher.
Thank you.
