Is this done on the server or the client?
Don't need to do anything on the server.
On the client that is being connected outside the office using Hamachi, I first start up Hamachi, and make sure I can "see" the AC xml file on the office server by navigating through the network, once the office network computers appear on my home computers network window. Then I open Amazing Utilities on the client computer, and reset the path to the database. Then I start Amazing Charts on the client, and when the dialog box opens asking me to find the database, I navigate through the displayed computers until I find the AC file on the server.
