I am desperately 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?
