...On the DMZ side, the physical interface is eno1 on which is layered bridge br0. br0 is assigned a static IP used by the physical node (host OS). VMs that should be on the DMZ get assigned br0 as their underlying network device. On the other network side, the physical interface is enp1s0, on which is layered bridge br2, on which is layered VLAN devices enp1s0.2 and enp1s0.3. None of these have IPs assigned in the host OS; The host is not supposed to have direct access to vlan2 or vlan3. VMs that are supposed to be on vlan2 and vlan3 are assigned either enp1s0.2 or...

...ed on NetworkManager. Scenarios (1) and (2) caused no problems, but (3) is giving me some headache. Let me take an example. The router in my office is a PC Engines routerboard running CentOS 7. It has three NICs, and I use two of these. WAN-facing NIC : # /etc/sysconfig/network-scripts/ifcfg-enp1s0 DEVICE=enp1s0 TYPE=Ethernet ONBOOT=yes BOOTPROTO=static IPADDR=192.168.1.1 NETMASK=255.255.255.0 LAN-facing NIC : DEVICE=enp2s0 TYPE=Ethernet ONBOOT=yes BOOTPROTO=static IPADDR=192.168.2.1 NETMASK=255.255.255.0 Third NIC is disabled : # /etc/sysconfig/network-scripts/ifcfg-enp3s0 DEVICE=enp3s0...

That doesn't make any sense at all. In what way are enp1s0.2 and enp1s0.3 layered on top of the bridge device? Look at the output of "brctl show". Are those two devices slaves o...
