Configuring bridge network in kvm (debian wheezy 7.2)
I am trying to run untangle 10 as a guest in kvm. My host system is debian 7.2
My problem is that I am unable to configure bridges/(virtual)NICS which are successfully identified by untangle. I would like to have two NICS in untangle. One for the internet connection and the other one for the internal network.
I already read several tutorials and how-to's and as far as I understood I have to configure network bridges.
I tried to configure them in /etc/network/interfaces
auto lo
iface lo inet loopback
iface eth0 inet manual
auto br0
iface br0 inet dhcp
bridge_ports eth0
I also tried to configure them via virt-manager and I also tried to use macvtap.
In all three cases I was not able to establish a connection via untangle. Is there anything I am missing/doing wrong?

if iptables is active, we can give the following rules.
sysctl -w net.ipv4.ip_forward=1
iptables -A FORWARD -m physdev --physdev-out br0 -j ACCEPT
iptables -A FORWARD -m physdev --physdev-in br0 -j ACCEPT
