Is it possible to NAT an Outside IP address on the internet to a single Inside IP address on my corporate LAN?
I have an application in my corporate network, which I would like to make available to an external party on the Internet. This application is configured to accept only connections from a specific IP Addresses (like an ACL).
The external party is using an ADSL modem which obtains a random IP Address assigned by the ISP. Therefore, I would like to use NAT on the outside (Internet), to give it a fixed IP Address on the inside on my corporate network.
Is this possible? If yes, what commands do I use to configure it?
Also, please advise if there is any danger in doing so, or what are my alternatives.
