Step 2: Configure DNS "Views"
You now need to fix the DNS problem that NAT creates. Users on the Internet need to access IP address 126.96.36.199 when visiting www.my-site.com and users on your home network need to access IP address 192.168.1.100 when visiting the same site.
You can configure your DNS server to use views which makes your DNS server give different results depending on the source IP address of the Web surfer's PC doing the query. Chapter 18, "Configuring DNS", explains how to do this in detail.
Note: If you have to rely on someone else to do the DNS change, then you can edit your PC's hosts file as a quick and dirty temporary solution to the problem. Remember that this will fix the problem on your PC alone.
