Hi all,I'm trying to implement opennebula on my personal lab as we have some projects with a colleague and it is nice to have disposable VMs, and also we are taking the oportunity to learn about OpenNebula to keep up-to-date :)
I would like to ask you a question I have, regarding networking, because I'm pretty sure that I'm missing something on the configurations but I cannot realize what.
We have the following infrastructure:  
  And the problem is that from the clients on subnet I can ping the VMs on, but the problem is that from the VM I can only ping,, and of the subnet, and all the other clients from some reason are not reacheable. 

I'm for sure missing something somewhere, but I cannot figure what. I had already enabled the ip4 forwarding on Host1 for all interfaces, and the following are the contents of /etc/network/interfaces file:# The loopback network interfaceauto loiface lo inet loopback
# The primary network interfaceallow-hotplug eth0iface eth0 inet static        address        netmask        gateway
auto Vbr0iface Vbr0 inet static        address        netmask        network        broadcast        gateway        bridge_ports eth1        bridge_fd 9        bridge_hello 2        bridge_maxage 12        bridge_maxwait 5        bridge_stp off
auto Vbr0:1iface Vbr0:1 inet static        address        netmask        gateway

And this is the vnet template I'm using for the VMs:onevnet show PublicVIRTUAL NETWORK 48 INFORMATIONID             : 48NAME           : PublicUSER           : oneadminGROUP          : usersCLUSTER        : -TYPE           : RANGEDBRIDGE         : Vbr0VLAN           : NoUSED LEASES    : 1
PERMISSIONSOWNER          : um-GROUP          : u--OTHER          : ---
RANGEIP_START       :         :

    ID USER     GROUP    NAME            STAT UCPU    UMEM HOST             TIME    92 admin    users    Debian 7.5 Base runn    0    256M HOMPLMPKRS   0d 11h23
If someone realize what I'm doing wrong and could give me an advise?May also, it is not the best way to bridge the connection of the VMs to the physical network, but I did not found other way of doing it on the documentation, or at least I did not understood.
Thanks in advance to all :)
