In my foray into the Cisco realm, I recently configured an ASA with access to the internet via static public IP (see blue shaded area of attached topology). The green shaded area of the topology represents a different subnet connected to the ASA. I configured the ASA to perform NAT for both of the following networks:
I verified that both of the above could reach the internet.
What I am having difficulty with is configuring both the router and the ASA to allow communication with each other from the 126.96.36.199 network to the 10.0.25.0 network. I've been reading through CCNA materials and have tried to follow lab examples, but can't seem to get it working. I enabled EIGRP on both and verified that routes are being advertised. I know I missing something.
My goal is understand the commands required under the different platforms (ASA 9.0 and IOS 15) and learn the most efficient way of establishing communication between the two subnets. Also, I need to fill my knowledge gaps.
Please see the attached topology, ASA configuration, and router configuration. Thank you all in advance for taking a look!
