Hetzner bridged network (OpenVZ)

[halperino]

Hello everyone. I've set up proxmox, but I'm having problems with networking. I have 1 additional IP (not a subnet) which I want to use to create a container. Is there anyone who could help me there and give configuration files of both the host and the container?(or a guide how to do that). Would really appreciate that and it might help others also. Here's the information of both the host and the additional container:

Host:
IP: X.X.X.100
GATEWAY: X.X.X.97
NETMASK: 255.255.255.224
BROADCAST: X.X.X.127

Container:
IP: Y.Y.Y.18
GATEWAY: Y.Y.Y.17
NETMASK: 255.255.255.248
BROADCAST: Y.Y.Y.23

Thank you.

have a look at
https://pve.proxmox.com/wiki/Network_Model

check the notes on "routed Configuration" and alternatively this one:
http://wiki.hetzner.de/index.php/Proxmox_VE/en

worked well when i still had a hetzner server.

I need to set up a bridged network (not routed). Here's my /etc/network/interfaces/ on both the host and the container I've created:

Host:

# network interface settings
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual
up route add -net X.X.X.96 netmask "Hosts netmask" gw "Hosts gateway" eth0 { Don't know why these 2 lines are there }
# default route to access subnet

auto vmbr0
iface vmbr0 inet static
address "Hosts IP"
netmask "Hosts netmask"
gateway "Hosts gateway"
bridge_ports eth0
bridge_stp off
bridge_fd 0

Container:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address "CT's IP"
netmask "CT's netmask"
network (not sure what I should type here to be honest)
broadcast "CT's broadcast"
gateway "CT's gateway"

Someone please help me there, I'm completely lost, literally checked every website...

Try to configure it as described here (worked for me using a /28 subnet):

Have you enabled ip forwarding within /etc/sysctl.conf ?
