Hi,

I have 2 servers: proxmox 1.3
On each server VM: network setup with venet on 10.0.0.0 network.
Each VM (10.0.0.x) can talk to each other and to the internet (and from the internet with NAT).

What I want is to have VMs on node 1 talk to VMs on node 2, so if I move a VM from one node to another one, my virtual network works (also being able to add more nodes in the future).

I guess I do have to setup a tunnel between the 2 nodes on the external (internet) IP adress. How to?
And then how to have the VMs talk to each other using the tunnel like connected to a swicth ?

Do I need to use & setup something with vde_switch ?

Thanks for your help.

Chris

There is no problem if you do NAT on your firewall (I guess you currently do NAT on the proxmox ve host?)
 
Yes i do NAT on the both ve hosts.

I just don't know what to do and how to it setup to have all my VMs on both ve hosts talk together.

Thanks
 
Hi,

I have a question that might be related to this.
Coming from planet VMware, I had there a networking option "host only", so that VMs could not talk to the outside world but still to each other and the host.

Scenario I think of: Have a VM with a VPN/Firewall appliance connected to the internet, making secure VPN access available to a host-only VM with windows, shielding it off.

Is this possible in PVE?

Thanks

Click to expand...

you can create a new bridge which is not connected to any physical network card (and use private IPs for the VMs)
 
Thanks, I looked at this, this is even more powerfull from a GUI point of view than VMware can do, great!
 
I have a similar question like the thread starter.
Let's say i got this cluster with master and node server: master (VM101: 10.0.0.1) <=> node (VM102: 94.23.xxx.xxx).
Now i need to connect from VM102 to VM101 and i do not want to assign a public ip to VM101. How to connect the two venet's?

simply route these two networks - either locally on your pve-host or on your default gateway(s)....
 
i forgot to say master and node server are just connected via the internet, so i guess i need something like vpn.
 
it is not clear to me why you setup a pve-cluster when both pve-hosts are not sharing the same networks - in this setup you cannot migrate vm's from one pve-host to the other one;

are the two pve-hosts directly connected to the internet or is there a firewall/router/l3-switch in between?

depending on your network infrastrukture and hardware you can configure a second network card to bring up both networks on both pve-hosts, use vlan tagging or subinterfaces if they are on the same layer2 network;

if both servers are on different geographic locations you need something like a vpn between these hosts - as you already mentioned before;
 
Both servers are directly connected to the internet with a single nic and the servers are on different geographic locations.
