Hi,
depends on your ISP. There are some similiar post about this in the forum.
See for starting here: http://forum.proxmox.com/threads/13841-Network-setup-for-Hetzner

Some People use iptable rules to send all traffic via the server-mac (needed by the ISP).
Perhaps you should ask the ISP.
If you ISP don't need special MAC-addresses simply use an briged device (vmbr0) for the VM/CT and use the right networkconfig inside the VM/CT.

I do not use Hetzner server ...

I did used the Proxmox Tutorial but now i have a big problem wich i do not know how to fix .

This is my : /etc/network/interfaces



auto lo
iface lo inet loopback


auto eth0
iface eth0 inet static
address 176.223.223.114
netmask 255.255.255.252
gateway 176.223.223.113
post-up echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp


auto vmbr0
iface vmbr0 inet static
address 176.223.224.88
netmask 255.255.255.248
bridge_ports none
bridge_stp off
bridge_fd 0




The OpenVZ Container Work but the KVM Machine does not work ... ( it does not have internet and can not ping ) how to make so even the KVM to work and have internet ... Please sir someone can help me ?

Assuming that you have only eth0 as interface connected to your ISP you should remove iface eth0 setup ( just iface eth0 inet manual )
On auto vmbr0 section add bridge_ports eth0
leave the ip address of vmbr0: 176.223.223.114
And use the IP addresses from the additional subnet directly inside the container ( except the gw ip address .89 that you'll configure as default route
on each VM ).
If this doesn't work then maybe your ISP has issued an additional subnet that is routed instead of directly connected and you should use something similar
in your last post but make sure you have forwarding active ( /proc/sys/net/ipv4/ip_forward ) and FORWARD chain in iptables accepts your forwarding.
I am pretty sure you don't need proxy arp, especially since you don't go further and publish some arp on a certain interface, you could drop that post-up from your config

Can you please give me the interface inforamtion full ... i do not know what to change exactly ...

Can you help me via TeamViewer or can i contact you somehow ... i will reward you for your true help please

 

[didraro]

I really do not know how to make please can you give me a more details information or if you can help me somehow entering to teamviewer ... or so i can contact you .

1st option:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

auto vmbr0
iface vmbr0 inet static
address 176.223.223.114
netmask 255.255.255.252
gateway 176.223.223.113
bridge_ports eth0
bridge_stp off
bridge_fd 0

And then you assign ip addresses to your VMs from 176.223.224.90 -> to 176.223.224.94 with default gateway to .89

Before you start configuring VMs you can try this to see if this is your correct setup:
ip addr add 176.223.224.90/29 dev vmbr0
ping 176.223.224.89

If ping is successful you can continue and setup these ip addresses to the VMs ( you should issue an ip addr del 176.223.224.90/29 dev vmbr0 )

If it doesn't work then you have to build a new vmbr1 with inet 176.223.224.89/29 and assign the rest of the IP addresses to your VMs..
One of these should work.
