How to convert internal network to external network

Hi All

I'm using openstack Icehouse which is configured to have one external network which works correctly. (Internal IP addresses are 10.0.0.0/24 and external floating IPs are 192.168.100.0/24)

There is also another network called "backhaul" which is internal and some VMs are interconnected using this network. (IP addresses are 192.168.1.0/24)

Right now I want to remove one VM and move its functionality to external PC connected to switch which interconnects controller and compute nodes. (IP would 192.168.1.100) The question is how to do it?

I tried to create a port for external router (192.168.1.10) which is pingable from VM but I am unable to ping the external PC

Thanks in advance Tomasz

Why not try something like this on your vm?

[root@localhost ~(keystone_admin)]# nova help  interface-attach
usage: nova interface-attach [--port-id ] [--net-id ]
                             [--fixed-ip ]


Attach a network interface to an instance.

Positional arguments:
                Name or ID of server.

Optional arguments:
  --port-id    Port ID.
  --net-id      Network ID
  --fixed-ip 
                        Requested fixed IP.
