Recently, I want to realize the Hyper-V new function in Windows Server 2012 so that will build a lab in virtualization environment. After installing a Server,I find out one question that cannot connect to the Internet then.
Why need to connect to the Internet? For window update or download tool from Microsoft Web Site!
Based on this reason, I think what method can been done simply and quickly? The answer will be Server with RRAS enabled, I think.
For realizing the difference between Windows Server 2008 (or R2) and Windows Server 2012, I study some articles from Microsoft and summary the process as the following “How to…”.
How to configure TCP/IP on Windows Server 2012?
Before configure an RRAS Server as Router, we need to configure the TCP/IP setting for the Internet network interface and for the intranet interface.
For internet setting, the reference is from ISP as public IP address, subnet mask and the default gateway. For intranet setting, the key point doesn’t define the default gateway (that is empty value) and its IP will belong to the default gateway in internal computer.
