How does ASA handle NAT incoming and outgoing traffics

Postby blin » Wed Aug 13, 2014 3:41 pm

In our Cisco ASA, we created 1-to-1 NAT (public ip x.x.x.174 and private ip 172.16.80.9) by following this how to: How to configure 1-to-1 NAT on Cisco ASA for a web server - Step by step with screenshots - http://www.howtocisco.com/cisco/pix&asa/asanat1.htm . However, if I google my ip on the web server, it shows x.x.x.194 which is the outside interface of the Cisco ASA. How does the Cisco ASA handle the NAT incoming and outgoing traffics? Do I need to change the web server TCP/IP settings, for example default gateway?

By design, all outgoing traffics go out via generic PAT, that’s why you are seeing your ip as interface (PAT ip)....
