[Xen-users] Xen network-route : mix Public and Private IP on a Front-Back architecture

[Christophe Bailleux <ch.bailleux@xxxxxxxxx>]

Hi everyone,

I need your help. I would like to create a front-back architecture with Xen.
My physical server has only one public Interface.

Currently, my DOM0 is using the network-route  configuration:

(network-script 'network-route netdev=eth0')
(vif-script     vif-route)


My DOM1 is configured with a public IP + proxy_arp with DOM0. DOM1 can connect any address on  Internet and is accessible from Internet too.
Now i would like to add a private IP address  on DOM1 in order to comunicate with DOM2, 3 and 4 who is configured with just a private IP address.


                                                                                                                                         -----(private IP) DOM4
                                                                                                                                       |
                                                                                                                                       |
Physical Eth0 (Public IP1)  --- DOM0 ----------- (public IP2 ) DOM1 (private IP1) --------------(private IP2) DOM2
                                                                                                                                       |
                                                                                                                                       |   
                                                                                                                                        -----(private IP) DOM3

To finish, i would like  DOM2, 3 and 4 to connect Internet via  DOM1 IP public Address.

Thanks for your help.

Lyes
