I use a systemd service file to setup a bridge for somewhat similar purposes, the sequence of commands I use is this: /usr/sbin/brctl addbr brkvm /usr/sbin/ip addr add 192.168.56.1/24 dev brkvm /usr/sbin/ip link set dev brkvm up after that, ip a s brkvm shows: 4: brkvm: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default link/ether fe:83:79:56:a3:a2 brd ff:ff:ff:ff:ff:ff inet 192.168.56.1/24 scope global brkvm valid_lft forever preferred_lft forever I have never used netctl so I can't help you there, in case you are wondering the complete service file is use is: [Unit] Description=Sets up a bride for use with virtual machines.
