Hello all, 

I am trying to setup a bridge. I have 3 virtual machines. The 1st acting as router, the second acting as bridge and the 3rd is the client, like the following diagram

                                                                   ROUTER                                 BRIDGE                                CLIENT

internet(ovirtmng network) ----- [eth0  router --eth1 ] -------[eth0 --[br0]-- eth1] -------[--eth Windows 10] 

The problem is that windows 10 is not able to connect the internet although is able to allocate ip. I use ovirt external network to connect the VMs to each other. 

It seems that Windows 10 sends ARP to BRIDGE, the BRIDGE sends the ARP to ROUTER but the replies are not passing the br0 when it comes a reply from ROUTER to Windows 10.

I use oVirt 4.3.6. Do you know what should be the issue ? Is there a chance that ovirt blocking the bridge?
