OVH failover Ip + proxmox windows guest

[HalfDead]

Greetings everybody,

The last couple of days I've been trying to look for a nice virtualization panel / system, and proxmox is what I ended up with and what I'm happy with.
However, I installed it on a clean Debian installation using the following guide:
https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Wheezy

The VM is running just fine and all, except for the network part. I've been strugling with this network issue for days now and checked out many guides / info ( from this forum aswell ), but couldn't seem to make it work.
tcpdump shows I'm pinging to an outside domain using the virtual machine ( google.nl, NIC=VMBR0 ):

94.23.xx.xx > ea-in-f94.1e100.net: ICMP echo request, id 1, seq 14, length 40

However, this always times out.
The DNS does not seem to work neither as I cannot simply ping to google.nl.

My host /etc/network/interfaces:

auto eth0
iface eth0 inet static
address 37.187.xx.xx
netmask 255.255.255.0
network 37.187.74.0
broadcast 37.187.74.255
gateway 37.187.74.254
pointopoint 37.187.74.254


auto vmbr0
iface vmbr0 inet static
address 37.187.xx.xx
netmask 255.255.255.255
bridge_ports none
bridge_stp off
bridge_fd 0
up ip route add 94.23.xx.xx dev vmbr0

Settings on Windows server 2008 guest:

IPV4:
 - IP Address: 94.23.xx.xx
 - Subnet mask: 255.255.255.255
 - Gateway: 37.187.74.254
IPV6:  disabled

I tried the host address as the gateway aswell, but didn't work.
Using the failover ip with .254 does not work neither.

The vm has a E1000 network adapter with the mac address I received as "Virtual MAC" from ovh.

Could perhaps somebody assist me?

What is your Virtual MAC Address?
What is the output of c:\>ipconfig of your Win 2008?

ipconfig: ( ip = failover ip, default gateway = host ip )

MAC address: 00:50:56:04:2b:dd

I can not see your MAC Address from your C:\>IPCONFIG. What you must make sure is:
- Your Windows MAC Address (from c:\>ipconfig) must same as your Virtual MAC

I assure you that it's the same MAC address as the virtual one.

EDIT: I updated the screenshot of ipconfig so you can see the mac.

bumpydump..
could it perhaps be because I'm now using the virtio interface instead of e1000?

EDIT: the note above is invalid, because now I'm using e1000 with the exact same problems.
however, I can ping my host machine and my host can ping the vm..
it's just not going out.

EDIT2: I fixed it..
removed the virtual MAC and it was working just fine..
