How to connect VM in Hyper V 2012 to the host network

I have a dell server with 4 nics running on a windows 2012 server running hyper v.

Although I have 4 nics but only once is connected to the LAN on a 192.x.x.x net – NIC #4. On the hyper v server I created a virtual switch which binds the virtual switch with NIC#4.

The network settings on the vm are pointing to this network config.

I have come across instructions on settings up an internal network. But seing that I only need com from the vm to the host not vice versa, I cannot get this to work with simply an external network configured.

I can’t ping anything but loopback. I want the vm to be on the same network as the host. I have setup the nic on the vm with the proper ip scheme.

Not sure what I am missing. I recall doing this before and not having to bridge any nics. I mention this because I read about many article which reference created an internal nic or bridging  the TWO NICS on the hyper host but what if I am only using one NIC? Although I have four, I am only using this as a dev box…not my mission critical server
