Hi all, Thanks for the time used to read my messages. I found the source of my issues and I'm creating an entry on my blog to summarize the issue and the resolution so it can easily be found by other people with the same issue.
I will share the link to the post here as soon as I finish with it. Best regards!

Hi Jaime, Thanks for your reply! Still not, I'm trying to figure it out right now. The ip route output is the following:root@Host1:~# ip route showdefault via 192.168.7.254 dev eth0192.168.7.0/24 dev eth0 proto kernel scope link src 192.168.7.1192.168.7.0/24 dev Vbr0 proto kernel scope link src 192.168.7.2192.168.254.0/24 dev Vbr0 proto kernel scope link src 192.168.254.254 Term1 routes:C:\Users\User1>route PRINTIPv4 Route Table===========================================================================Active Routes:Network Destination Netmask Gateway Interface 0.0.0.0 0.0.0.0 192.168.7.254 192.168.7.50 10.142.168.0 255.255.255.0 On-link 192.168.7.50=========================================================================== 192.168.7.254 routes:admin@Gateway:/tmp/home/root# ip route show130.255.155.1 dev eth0 scope link192.168.7.0/24 dev br0 proto kernel scope link src 192.168.7.254130.255.155.0/24 dev eth0 proto kernel scope link src 130.255.155.33192.168.254.0/24 via 192.168.7.2 dev br0 metric 1127.0.0.0/8 dev lo scope linkdefault via 130.255.155.1 dev eth0 I'm thinking that this issue could be caused as I'm routing the traffic to the virtual machines from 192.168.7.254 (The gateway of my network) to Host1 through 192.168.7.2, but actually the traffic comming from Host1 is through 192.168.7.1, maybe that could be causing my problem?

To: thedragonsreb...@hotmail.com CC: users@lists.opennebula.org Hi, did you manage to figure this out? otherwise, can you send us the output of "ip route" in the VM, Host 1 and Term 1? cheers, Jaime On Wed, Jul 30, 2014 at 6:30 PM, Diego M. <thedragonsreb...@hotmail.com> wrote: 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 192.168.7.0/24 subnet I can ping the VMs on 192.168.254.0/24, but the problem is that from the VM I can only ping 192.168.7.1, 192.168.7.2, and 192.168.7.254 of the 192.168.7.0/24 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 interface allow-hotplug eth0iface eth0 inet static address 192.168.7.1 netmask 255.255.255.0 gateway 192.168.7.254 auto Vbr0iface Vbr0 inet static address 192.168.7.2 netmask 255.255.255.0 network 192.168.7.0 broadcast 192.168.7.255 gateway 192.168.7.254 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 192.168.254.254 netmask 255.255.255.0 gateway 192.168.7.2 And this is the vnet template I'm using for the VMs: onevnet show PublicVIRTUAL NETWORK 48 INFORMATION ID : 48NAME : Public USER : oneadminGROUP : usersCLUSTER : - TYPE : RANGEDBRIDGE : Vbr0 VLAN : NoUSED LEASES : 1 PERMISSIONSOWNER : um- GROUP : u--OTHER : --- VIRTUAL NETWORK TEMPLATEBRIDGE="Vbr0" DESCRIPTION=""DNS="192.168.7.254" GATEWAY="192.168.254.254"NETWORK_ADDRESS="192.168.254.0" NETWORK_MASK="255.255.255.0"PHYDEV="" VLAN="NO"VLAN_ID="" RANGEIP_START : 192.168.254.1 IP_END : 192.168.254.253 USED LEASESLEASE=[ MAC="02:00:c0:a8:fe:01", IP="192.168.254.1", IP6_LINK="fe80::400:c0ff:fea8:fe01", USED="1", VID="92" ] VIRTUAL MACHINES 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. More detailed information about the templates I'm using, below is the "public" network template(provides leases of 192.168.254.0/24), that is the one I want to bridge to the local network (192.168.7.0/24).
