Network was broken on all virtual machines

Today the network in all virtual machines was droped.

I use 3 hosts, 5 virtual machines with private address.

Ping between virtual machines - successful.

Ping between host and virtual machine - not successful.

Ping between hosts - successful.

I use static IP address.

I use vmware hypervisor.

Guest operating system - Microsoft Windows.

I found http://communities.vmware.com/thread/59845?start=45&tstart=0 , but it don't help me.

Do you have any ideas to solve this problem?

VMWare uses all of the same basic networking principles in the physical world, just virtualized.  It doesn't route for you.

There are network between hosts and other network. There are network between vms.

Ping: host to host - successfully.

Ping: vm to hosts - destination host unreachable.

No such network between virtual machines and hosts.

as per netwwork diagram, i cant see both host netork and vm network to be on different subnet, as there is no vlan id, so u have configured different subnets for host and vm network on same uplink without vlan's?

Not sure if you have the capabilities of doing this in your environment, but if you want to isolate your management interfaces, here is how it could be done in general.

Create separate VLANs for each of your subnets using VLAN tagging on your switch (that is if you have a managed switch).  Connect your router to both VLANs.  Ensure you have routes between each VLAN/Subnet and setup your ACL to allow access to the Management Interface.  This link should tell you what ports you need.

Otherwise, put the Management Interface into the same subnet as your other network.
