Hello, I'm recently stumbled over the libvirt network filter capabilities and got pretty excited. Unfortunately I'm not able to get the the "clean-traffic" filterset working. I'm using a freshly installed Debian Stretch with libvirt, qemu and KVM. My config snippet looks as follows: sudo virsh edit <VM> [...] <interface type='bridge'> <mac

Hi Sam, You can find the rules by below command, and it looks as below: # ebtables -t nat --list Bridge table: nat Bridge chain: PREROUTING, entries: 2, policy: ACCEPT -j PREROUTING_direct -i vnet0 -j libvirt-I-vnet0 Bridge chain: OUTPUT, entries: 1, policy: ACCEPT -j OUTPUT_direct Bridge chain: POSTROUTING, entries: 2, policy: ACCEPT -j POSTROUTING_direct -o vnet0 -j libvirt-O-vnet0 Bridge chain: PREROUTING_direct, entries: 0, policy: RETURN Bridge chain: POSTROUTING_direct, entries: 0,...
