If you say Y here, then your Linux box will be able to act as an |
|
Ethernet bridge, which means that the different Ethernet segments it |
|
is connected to will appear as one Ethernet to the participants. |
|
Several such bridges can work together to create even larger |
|
networks of Ethernets using the IEEE 802.1 spanning tree algorithm. |
|
As this is a standard, Linux bridges will cooperate properly with |
|
other third party bridge products. |
|
|
|
In order to use the Ethernet bridge, you'll need the bridge |
|
configuration tools; see <file:Documentation/networking/bridge.rst> |
|
for location. Please read the Bridge mini-HOWTO for more |
|
information. |
|
|
|
If you enable iptables support along with the bridge support then you |
|
turn your bridge into a bridging IP firewall. |
|
iptables will then see the IP packets being bridged, so you need to |
|
take this into account when setting up your firewall rules. |
|
Enabling arptables support when bridging will let arptables see |
|
bridged ARP traffic in the arptables FORWARD chain. |

|
To compile this code as a module, choose M here: the module |
|
will be called bridge. |

If unsure, say N. |

If you say Y here, then the Ethernet bridge will be able selectively |

forward multicast traffic based on IGMP/MLD traffic received from |
|
each port. |
