Connecting to a bridged host

I have installed OpenNebula on two Ubuntu 16.04 VM, where one is the controller node, and the other is the compute node. I created the following bridged interface on the Compute node:

auto br0
iface br0 inet static
address 192.168.1.65
network 192.168.1.0
broadcast 192.168.1.255
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 192.168.1.4 8.8.8.8
dns-search dasilva.network
bridge_ports enp0s3
bridge_fd 9
bridge_hello 2
bridge_maxage 12
bridge_stp off

When I start another VM machine through the OpenNebual web GUI, which is using the bridge interface, I can ping the new VM from the Compute Node, but not from any other node that is on the same network or from the node to any other node on the network.

MyNetwork <----> br0 <---->VM

Here is the output fron the compute node:

Code: Select all

$ brctl show

Bellow is the Virtualbox network setting for the compute Node:

NIC 1: MAC: 080027BFD3EE, Attachment: Bridged Interface 'enp3s0', Cable connected: on, Trace: off (file: none), Type: 82540EM, Reported speed: 0 Mbps, Boot priority: 0, Promisc Policy: deny, Bandwidth group: none

What might be the problem and how can I make it work?
