Allowing access to a single internal computer for a small block of public IP addresses using Cisco ASDM?

Last Modified: 2015-04-30
Hi, I am trying to use the Cisco ASDM to simply add a ACL (supported by a NAT) to allow traffic to and from a single internal IP to a select group of public IP addresses.

What is the best way to do this?  Note I want to use the GUI.  Command line is cool, but I don't use this thing enough to care to use the command line or internalize all of these commands.  Plus, I like the GUI as I can better visualize the context of things I am trying to do and how they relate to existing things.  

I can see in source for access rules, there is a default to any, but it looks like you can pick and tailor things.  Of some of the options, it just lists a bunch of internal networks.  Is there a way that I can manually add a public IP address network ID and corresponding network mask?  IE to say, allow traffic to this internal server, but only from these IPs?
