Thanks Ruben for the reply. <div><br></div><div>You are correct about the IP in the network, as soon as I reconfigured the vnet to be in the 10.0.0.X space instead of 192.168.100.X I could start ssh from outside.

<br>
I have a working installation of OpenNebula 3.8.3, but despite many<br>
efforts I still cannot ssh from the host into the VMs.<br>
<br>
All hosts have:<br>
- an eth0 interface listening to the internal network of my institution<br>
- an eth1 interface for a private switched LAN only between the hosts<br>
that compose the OpenNebula cloud. The hosts have IPs 10.0.0.X on this<br>
network.<br>
<br>
On all the machines I have run the following commands:<br>
<br>
brctl addbr br1<br>
brctl addif br1 eth1<br>
ifconfig eth1 down<br>
ifconfig eth1 0.0.0.0 up<br>
ifconfig br1 10.0.0.X/24 up (where X=1,2,... depending on the host).<br>
<br>
I then defined in Sunstone a virtual network as follows:<br>
=============<br>
ID : 0<br>
NAME : vn-private<br>
USER : oneadmin<br>
GROUP : oneadmin<br>
CLUSTER : cluster<br>
TYPE : RANGED<br>
BRIDGE : br1<br>
VLAN : No<br>
PHYSICAL DEVICE:<br>
VLAN ID :<br>
USED LEASES : 2<br>
<br>

OWNER : um-<br>
GROUP : ---<br>
OTHER : ---<br>
<br>

<br>

IP_START : 192.168.100.1<br>
IP_END : 192.168.100.128<br>
<br>

LEASE=[ IP="192.168.100.13", MAC="02:00:c0:a8:64:0d", USED="1", VID="14" ]<br>
LEASE=[ IP="192.168.100.37", MAC="02:00:c0:a8:64:25", USED="1", VID="41" ]<br>
=============<br>
<br>
Now: using VNC, I see that the two VMs .13 and .37 can correctly ping<br>
each other.However, if I login to any host and do 'ssh<br>
<a href="mailto:root@192.168.100.13" target="_blank">root@192.168.100.13</a>' it does not connect to the VMs.<br>
<br>
I tried then 'route add -net 192.168.100.0 netmask 255.255.255.0 dev<br>
br1' and 'route' shows correctly<br>
<br>
Destination Gateway Genmask Flags Metric Ref Use Iface<br>
192.168.100.0 * 255.255.255.0 U 0 0 0 br1<br>
<br>
but still ssh does not work.<br>
<br>
Can someone help me? My ultimate goals are:<br>
1) to be able to ssh from the host into the VMs.<br>
2) if possible, give internet connectivity to the VMs through eth0.<br>
<br>
Thanks,<br>
