Router with one DHCP and one static IP doesn't route

Hi, all,

this post I already published in the Windows 2012 General forum but I need more info or advice:

http://social.technet.microsoft.com/Forums/windowsserver/en-US/add7b68c-ea88-434a-bb06-37edf524399a/router-with-one-dhcp-and-one-static-ip-doesnt-route?forum=winserver8gen

I observed some strange behavior in my VM environment on my Laptop; perhaps somebody can give me a hint what I did wrong.

Scenario:

- Laptop "Host" (Alienware M18x, 32 GB RAM) with Windows Server 2012 R2, connected to Internet via WLAN
    - WLAN IP address supplied by DSL router via DHCP: 192.168.1.100/24, Gateway 192.168.1.1
    - HyperV Server
       - External Switch (Virtual Switch Manager: "External network" directing to the WLAN adapter)
       - Internal Switch (Virtual Switch Manager: "Internal network")
       - Bridge between external switch and WLAN adapter
       - Two virtual machines
          - "Router": Is intended to route network traffic between external switch/"Host" and the internal switch/private network and the machine called
             - 1 NIC connected to External Switch with DHCP (right now: IP address 192.168.1.101/24, Gateway 192.168.1.1)
             - 1 NIC connected to Internal Switch using a static IP address (10.0.0.1/8)
             - Not member of the domain
             - RRAS configured
          - "DC": Domain Controller
             - 1 NIC connected to Internal Switch using a static IP address (10.0.0.2/8), Gateway (10.0.0.1)
 - DSL Router as WLAN access point, Gateway, IP address 192.168.1.1

Scenario checked by four crying eyes!

Problem:

On machine "Router":

ping 192.168.1.101 ("Router"): OK
 ping 192.168.1.101 ("Host"): OK
 ping 192.168.1.1 ("DSL Gateway"): OK
 ping 10.0.0.1 ("Router"): OK
 ping 10.0.0.2 ("DC"): OK

On machine "Host":

ping 192.168.1.100 ("Host"): OK
 ping 192.168.1.101 ("Router"): OK
 ping 10.0.0.1 ("Router"): fail
 ping 10.0.0.2 ("DC"): fail

On machine "DC": Can also ping the external Network on "Router" but not more!

ping 192.168.1.100 ("Host"): fail
ping 192.168.1.101 ("Router"): OK
 ping 10.0.0.1 ("Router"): OK
 ping 10.0.0.2 ("DC"): OK

So the router seems not to route the requests!

If I provide only static IP addresses on "Router", everything works fine!

Goal:

I want to grant "DC" Internet Access as well as access to network shares on "Host".

But I need my external network to connect to any Network (DSL Router or other Interfaces), wherever I am working with my laptop. This means the IP address changes quite often. Still I do not want to check or reconfigure the router the moment I connect to a network.

Does anyone have an idea what might have gone wrong? Any configuration I've missed?

In my post in the Windows Server General forum the user Bill suggested me to configure extra routing. What do I have to do there?

Best regards

Jens-Peter
