Network configuration for VM without public IPs

[Mario Giammarco <mg...@gmail.com>]

Hello,
I have a private network I have no public ips.
I have guest and public network configured as 10.3.6.x and 10.3.5.x.
I am using advanced zone networking.
I have my router that does nat on 10.3.5.1 and 10.3.6.254.

My vm get an address in the range 10.3.6.x and I see that ip 10.3.6.1 is
assigned but not by me. I assume it is a system VM for firewall.

I would like to simply have my vm communicate with other real client and
servers on my private network.
The first thing you usually do on non-cloud virtualization systems.

How can I do it with cloudstack?

Thanks in advance,
Mario

Hi,

If you look at the details of the VM running , has the vm be allocated a private ip address?
Have you setup the firewall rules inside cloudstack to allow for the VM's to talk to each other or the ip's of the real clients and servers?

You could do that of course. (we do it actually that way in a private
cloud setup).

I am not sure if I understand your setup correctly but it looks your
setup would not work since the networks 10.3.6.0/24 and 10.3.5.0/24 are
used for "internal" (Isolated, dhcp from virtual router) and external
(public ip network).

Could you reconfigure the isolated network with a different network then
used for public e.g. 10.1.1.0/24 ? So you the VMs will get a different IP.

Than you can either create a static nat between your "public net"
10.3.5.0/24 and your internal 10.1.1.0/24 or a portforwarding just using
the user API/UI
