newbie: how to configure network interfaces veth bridged?

[melinameline]

Hi,
i'm newbie on proxmox virtualisation.
i installed proxmox 1.9 on a debian squeeze, and create two CTs to contain my two web servers.

the physical caracteristics of the host machine are:

1- 2 network cards (physical interfaces),
2- 2 hard disks (500Go each one),
3- 8Go of RAM,

i don't now how to configure my two network cards to be able to give public adresses to the VMs (CTs) to be viewed from outside.

i have two network cards: eth0 and eth1 on the host machine, so:
eth0 have a private ip adresse as 192.168.0.2,
and eth1 is linked to the to interfaces of my servers (CTs), so i dont now how to configure the bridge or bridges (because i don't now if i must use one or two) on this NI.

that's what i put in the /etc/network/interfaces host file:

# network interface settings
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
        address  192.168.0.1
        netmask  255.255.0.0
        gateway  192.168.0.1
        broadcast  192.168.0.255
        network 192.168.0.0
        dns-nameservers 192.168.0.1
        dns-search mydomain.org
# dns-* options are implemented by the resolvconf package, if installed

auto eth1
iface eth1 inet manual

auto vmbr0
iface vmbr0 inet manual
       bridge_ports eth1
       bridge_stp off
       bridge_fd 0

auto vmbr1
iface vmbr1 inet manual
       bridge_ports eth1
       bridge_stp off
       bridge_fd 0

and in the /etc/network/interfaces file of the first VM:

auto lo
iface lo inet loopback

#auto eth1
#allow-hotplug eth1
#iface eth0 inet static
#        address IPpublic1@
#        netmask NetmaskPublic@
#        network Network-Public@
#        broadcast Broadcastpublic@
#        gateway IPpublicgateway@
#        # dns-* options are implemented by the resolvconf package, if installed
 #       dns-nameservers DNSIpPublic@
  #      dns-search mydomain.ory

and the same on the second VM:

auto lo
iface lo inet loopback

#auto eth1
#allow-hotplug eth1
#iface eth1 inet static
#        address IPpublic2@
#        netmask NetmaskPublic@
#        network Network-Public@
#        broadcast Broadcastpublic@
#        gateway IPpublicgateway@
#        # dns-* options are implemented by the resolvconf package, if installed
 #       dns-nameservers DNSIpPublic@
  #      dns-search mydomain.ory

but it deosn't function, it shows me that eth1 is already a member of a bridge; can't enslave it to bridge vmbr1.
so, how can i configure the eth1 to link to the two VMs public interfaces?
Thanks

Hi,

...

Before going further:

• 1.9 is based on Lenny, do not install this on Squeeze
• 1.9 is really outdated and not maintained since a long time, do not use it anymore
• => use always latest stable, see http://pve.proxmox.com/wiki/Roadmap
