How to make a white IP visible from the local network?

Question

Computer networks

Good afternoon. There is a machine on Win2008 with a white IP, a web server was raised, port forwarding was configured on win2008 via ICS, everything is visible from the Internet (the site opens through the browser), but from the local network if you go to the white IP nothing opens, what needs to be done what it would be visible from the local network. The network is domain, there is a domain controller and a dns server on win2008 on another machine, help me set everything up correctly. Thanks a lot.

Answer 1

You do not need this - go inside the network to a gray address.
In fact, people usually go by name, not by address. To do this, within the DNS network must give private addresses, and outside - white. Everything will be transparent for the user - in both cases, he will follow the same name.

Answer 2

the machine with win2008 has a white IP. your machine in LAN is grey. thus there are two networks. The router is responsible for access from one network to another. or possibly multiple routers if there are more than two networks.
you need to configure routing on the router. how exactly - depends on the network topology, which is tactfully not mentioned in your question.
