Setup:

Raspberry PI with raspbian os installed connected via Ethernet cable to my PC (windows 10)

Ethernet connection that are created got ip range 169. ... meaning cannot get DHCP server.

In my network configuration under IPv4 i got Obtain IP address automatically and Obtain DNS server automatically.

I can see green lights under Ethernet cable on both raspberry pi and PC.

What i am doing wrong? Why my windows cannot obtain an IP automatically?

You are getting link-local address assignment on the Raspberry Pi because your Windows network connection is not shared.

In general this is called a network bridge. On Windows, a network bridge is created when the user selects "Allow Other Network Users to Connect through This Computer’s Internet Connection"

See this question Share Windows computer internet connection with Raspberry Pi

On Automatic IP address assignment

DHCP

The usual method of automatically assigning IP addresses is through the use of a network DHCP server. In many home networks, the DHCP server is included on the router... which is usually, but doesn't need to be, also a WiFi Router.

So, if your question is:

How do I get my Raspberry Pi to have an automatically assigned address on my LAN while it is connected via an Ethernet cable to my Windows PC?

the answer is:

Create a network bridge between your LAN connected network interface on your Windows PC and your Ethernet connected Raspberry Pi.

If you do not want your Raspberry Pi to have Internet access, you can configure a static lease on your router for the Pi and configure your router's firewall rules to disable FORWARDING for statically assigned lease address.

Of course, methods for setting up a static address and configuring the firewall will depend on your individual router.

  • I am not sure i understand. I don't want raspberry to be able to connect to internet. I want to connect to raspberry in my internal network. – Farseer Nov 25 '17 at 21:56
  • After you added details i understood everything. All working now. My assumption that windows will by default will forward DHCP request to router was wrong. Thanks. – Farseer Nov 25 '17 at 22:33
