Unable to Ping VMs

[garethEds]

Hi All,

 

Need to pick your collective brains. I have two servers in a cluster. They can see each other, all can ping each other on all networks.

 

However, when I move a virtual machine to the second server, it cannot be pinged from the outside world or itself. Live and Quick migration both work. I have a VM Traffic teamed network - which can ping the other servers and can ping the main network. Just nobody can ping the VMs on that second server.

 

The management network is separate from the VM Traffic network - but I cannot for the life of me work out how the VM traffic gets out onto the network. It clearly does from the first server but I cannot find the difference between the first and second servers.

 

I've checked the HyperV server virtual switch settings and all seem ok.

 

On the first server it can.

 

What am I missing?
