Cisco AnyConnect loses networks when using Hyper-V External Network Virtual Switch

Hi,

 

I am using Cisco AnyConnect on my physical machine to connect to networks within the office and out and about.  I now have a requirement to setup a new Virtual Switch in Hyper-V using an External Network.  However as soon as I select the network card that has the internet connection from within Hyper-V, AnyConnect loses the connection from the dropdown list of available connections.

 

For example if I am connected to the internet using my wireless network (named: WiFi_Network) I am happy and can browse the web to my hearts content.  The moment I configure my virtual switch to use WiFi_Network AnyConnect can no longer see the network adapter and I am disconnected from the internet.

 

Is there a way to get both a Virtual Switch configured to use an External network and have Anyconnect working on the same network at the same time?

Hi

 I´m trying hard to correlate this two things:

 

"I am using Cisco AnyConnect on my physical machine to connect to networks"

"new Virtual Switch in Hyper-V using an External Network"

What the hack your physical machine is related to your virtual switch and being affected by changes made on the virtual environment?

 Can you explain a bit better how things interconnect on your network?

Hi Flavio and thank you for the response.

Within Hyper-V a Virtual Switch configured to use an External Network is one that is bound to a specific Network Adapter on the Physical Machine.  As Soon as this binding happens all wireless networks will disappear from AnyConnect.

In fact if I bind one of my wired network ports to the the Virtual Switch the same thing happens, the network connection will vanish from AnyConnect.

I am not using a Virtual Machine for AnyConnect, this is all on the Physical Machine.

I think this is the normal behavior because of the use of virtual network adapters. You can (typically) only have one active at a time.
You might want to open a TAC, maybe they can tune/fix this in an updated AnyConnect.
