Notes: I suggest to move the netctl-specific parts of this article into a subsection of "Network bridge" (Discuss in Talk:Bridge with netctl#)

Make sure netctl is installed.

Copy `/etc/netctl/examples/bridge` to `/etc/netctl/bridge`.

In this example, we create a bridge called `br0` which has real Ethernet adapter `eth0` and (optionally) a tap device `tap0` connected to it. Of course, edit `br0`, `eth0` and `tap0` to your needs.

    /etc/netctl/bridge

    Description="Example Bridge connection"
    Interface=br0
    Connection=bridge
    BindsToInterfaces=(eth0 tap0)
    IP=dhcp

This example creates a statically assigned bridge called `br0` which has real Ethernet adapter `eth0` connected to it. Edit `Interface`, `BindsToInterfaces`, `Address`, and `Gateway` to your needs.

     /etc/netctl/bridge

    Description="Example Bridge connection"
    Interface=br0
    Connection=bridge
    BindsToInterfaces=(eth0)
    MACAddress=eth0
    IP=static
    Address='192.168.10.20/24'
    Gateway='192.168.10.200'
    ## Ignore (R)STP and immediately activate the bridge
    SkipForwardingDelay=yes

Tip: If you are using static IP, see man pages of netctl, and also edit `/etc/resolv.conf` if necessary.

You can bridge any combination of network devices editing `BindsToInterfaces` option.

If any of the bridged devices (e.g. `eth0`, `tap0`) had dhcpcd enabled, stop and disable the `dhcpcd@eth0.service` daemon. Or set `IP=no` to the netctl profiles.

Finally, start and enable your `/etc/netctl/bridge`.
