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.txt>
|
|
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.

|
---help---
|
|
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.
|
|
|
|
Say N to exclude this support and reduce the binary size.
|
|
|
|
If unsure, say Y.
