Network issues

[florian.gstoettenbauer]

Hi!

I installed the latest Proxmox-version and use a new installed Microsoft Windows Server 2012 R2 Standard Dreamspark German as guest-OS.
The NIC of the guest was configured in Proxmox with "Intel E1000", bridged mode vmbr0 (the default setting by Proxmox).
Windows-Guest has full access to the internet, but when I tried to install a network-printer, windows couldn't find it. The strange thing is - I can ping "10.0.0.11" (another PC), "10.0.0.13" (Proxmox-Host) and access my NAS on "10.0.0.10". Only my printer with static IP 10.0.0.12 can't be even pinged ("host unreachable")?
Has anyone ever had the same issues? How can i fix this problem?

/etc/network/interfaces on my Proxmox-host has the following settings:

# network interface settings
auto lo
iface lo inet loopback

iface eth0 inet manual

auto vmbr0
iface vmbr0 inet static
address 10.0.0.13
netmask 255.255.255.0
gateway 10.0.0.2
bridge_ports eth0
bridge_stp off
bridge_fd 0

Thank you for your help!
