I've got an interesting situation trying to get NAT working properly with a Cisco ASA 5510.
The Outside interface of the ASA is set as a public routable assigned to us by our ISP. Our ISP also routes several other networks (3 class C networks) to us. What I need to do is to NAT all of the IPs in these additional subnets to one single IP on the internal network.
Some other details:
Internal Network: 10.1.1.0/24
Internal Host (CSS11501): 10.1.1.65
ASA Inside Interface IP: 10.1.1.1
ASA Outside Interface IP: 22.214.171.124
ASA Outside Network: 126.96.36.199/29
Additional Networks: 188.8.131.52/24, 184.108.40.206/24, 220.127.116.11/24
NB: Networks/IPs have been changed to protect the innocent.
I have tried implementing the above with dynamic NAT rules with the "real" IPs on the outside interface and a single-IP NAT pool on the inside interface, but it doesn't seem to be working.
Any pointers on how I can achieve such a setup with a Cisco ASA5510?
