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

Installation

Install the netctl package from the official repositories.

Configuration

  • 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 br0, eth0, Address, and Gateway to your needs.
 /etc/netctl/bridge
Description="Example Bridge connection"
Interface=br0
Connection=bridge
BindsToInterfaces=(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.
