Docker + firewalld
...of the Docker containers. I ran the following command:
firewall-cmd --direct --permanent --add-rule ipv4 nat POSTROUTING 0 -i
br+ -o eth0 -s 172.16.26.0/24 -j ACCEPT
However, the firewall rules for NAT are:
-A POSTROUTING -s 172.16.26.0/24 ! -o br-ee1ac3f6bbaf -j MASQUERADE
-A POSTROUTING -j POSTROUTING_direct
-A POSTROUTING_direct -s 172.16.26.0/24 -i br+ -o eth0 -j ACCEPT
With this, it always goes via MASQUERADE first, without hitting the
POSTROUTING_direct chain. Is there a way to add this rule on top of
POSTROUTING?

Network filters with clean-traffic not working on Debian Stretch
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
