Most of the friendly distros use NetworkManager. You can create a permanent bridge (which stays between reboots) with NM with just 3 easy commands, no editing of config files: Add a new bridge: nmcli con add type bridge ifname br0

Create a slave interface: nmcli con add type bridge-slave ifname eno1 master br0

Turn on br0: nmcli con up br0 Thanks for your incredible guide. I had never understood what a bridge really was before you explained it. It was magic before. Now it makes sense.

ip link add name br0 type bridge
ip link set eno1 master br0

ip addr add 192.168.0.65/24 dev br0 brd 192.168.255.255

ip link set up eno1
ip link set up bro0
