Force Windows 8 to use UMTS

Question

My situation:

I am running (evaluating) Windows 8 (RTM) on my Laptop. I am connected to a LAN which has NO access to the internet (DEV-LAN). I am running a virtual machine (VMware Workstation) which is connected via Bridge Mode to the DEV-LAN. This virtual machine has no access to the internet.

Before, with Windows 7 I was able to connect the host via UMTS to the internet while the virtual machine still was connected to the DEV-LAN. So I could keep working within the virtual machine while doing research (MSDN, Google, Stackoverflow) in the internet on the host.

When I now connect the Windows 8 host to the mobile broadband, nothing changes in the runtime behaviour. The whole Network communication is still running over DEV-LAN. Windows 8 tells me in the Network Sidebar that mobile broadband is connected, but it does not use it. When I remove the network plug of DEV-LAN, THEN the broadband connection will be used. But then obviously, I cannot work in my virtual machine, which depends on DEV-LAN.

Question:

Is there any switch in windows 8 that I can use to tell the system to use broadband over LAN, when available?

Thanks a lot!

edit for the comment of pst: the following metrics are given

IPv4-Routentabelle

Aktive Routen:

Answer 1

It finally works :-) I set the metric of my LAN-Adapter to 999 and everything is as I want it to be.

Any change of the UMTS Adapter to a lower metric was unsuccessful. Even when I set the metric to 1 or 5 or 10, netstat /rn told me a metric > 50.

So when I cannot lower the one metric, I have to raise the other one ;-)

The metric can be easily changed like follows:

1. System Settings
2. Network and Internet
3. Network Connections
4. Ethernet -> Context Menu -> Properties
5. Select Internet Protocol (v4) -> Properties
6. Advanced
7. Automatic Metric off and manually set to 999
