Hi,
and how came the packets from eth0/vmbr0 to vmbr1?? Is this done by iptable.up.rules?

Look with tcpdump what happens if you ping your VM like
Code: 
tcpdump -i eth0 host ip.of.win.vm
tcpdump -i vmbr1 host ip.of.win.vm
I guess you don't see any incomming traffic on vmbr1?! Look also with "ifconfig vmbr1".

This is why Dietmar wrote "Why do you create vmbr1 at all?".

,, I only want to know how can i write the correct ( /etc/network/interfaces )
and how can i add ( IP ) for VM ( windows OS 2008r2 )

5.9.185.144 / 28
and my main IP :
[TABLE="class: cms_table_ip_list"]

Hi,
this depends on your hoster - how does the network are used.
Simply two networks on one port? Routing via main IP? Must all packets came from the main-IP (NAT)?

Ask your hoster, and/or use the search function of this forum (also pve1.x). There are some examples for hetzner.

my data center is : ( hetzner )
... i just want add ip for my Vm no more .. Ithink this is too easy .. why it is complicated ?

It seems your extra IPs are on a different subnet to the main, something common with Hetzner. If you have setup your main IP correctly and have internet access on it, try something like:

up ip route add 5.9.185.144/28 via 5.9.185.xxx dev eth0

at the end of your /etc/network/interfaces file. Replace .xxx with the gateway address of your extra ips and eth0 with whatever address your main server is using.
 
so it will be :

# network interface settings
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 5.9.70.194
netmask 255.255.255.224
gateway 5.9.70.193
broadcast 5.9.70.223
post-up iptables-restore < /etc/iptables.up.rules
pointopoint 5.9.70.223

auto vmbr0
iface vmbr0 inet static
address 5.9.185.144
netmask 255.255.255.240
gateway 5.9.70.194
bridge_ports none
bridge_stp off
bridge_fd 0

auto vmbr1
iface vmbr1 inet static
address 5.9.185.145
netmask 255.255.0.0
bridge_ports none
bridge_stp off
bridge_fd 0

up ip route add 5.9.185.144/28 via 5.9.185.xxx dev eth0
