Hyper-v not pinging from VMs Primary gateway?

Question

Windows

The essence of the problem is Windows 2008 R2, the network is connected to one network card, there is a 32 IP range allocated, an external virtual network card has been created.

On Windows 2008 R2 itself, the network is configured like this:

IP:88.210.215.66<br/>
MAss:255.255.255.224<br/>
IP_gatwey:88.210.215.65

Everything works fine, the Internet is available and the server is accessible from the Internet.

A virtual machine was raised with CentOS 5.5 with an integration package, network setup:

IP:88.210.215.67<br/>
MAss:255.255.255.224<br/>
IP_gatwey:88.210.215.65

Between themselves, everything is pinged normally, when I try to ping 88.210.215.65 I get Destination Host unreachabl, and the Internet address 88.210.215.67 does not ping. Firewall is disabled for now.

For the second day I have been suffering, I can not find any information, can someone tell me what the problem might be.

PS Raised a second virtual machine with an outdated network adapter, ping on GatWay also does not work

Answer 1

What settings are on a real network card? On my main (physical card) in the settings, I set active only the Virtual Network Switching Protocol, and on the virtual one I already configured the parameters for the physical server. All virtual machines perfectly work and respond from everywhere.

Answer 2

Deliver in tsentos the gateway 66 and configure on the 66th route.
